TPS22919 5.5 V, 1.5 A, 90 mΩ Load Switch

Posted on by mixos

Texas Instruments’ self-protected switch features controlled rise time and adjustable output discharge

Texas Instruments’ TPS22919 device is a small, single-channel load switch with a controlled slew rate. The device contains an N-channel MOSFET that can operate over an input voltage range of 1.6 V to 5.5 V and can support a maximum continuous current of 1.5 A. The switch ON-state is controlled by a digital input that is capable of interfacing directly with low-voltage control signals. When power is first applied, a smart pull-down is used to keep the ON pin from floating until the system sequencing is complete. Once the pin is deliberately driven high (>VIH), the smart pull-down will be disconnected to prevent unnecessary power loss.

The TPS22919 load switch will protect itself from short-circuit events on the output. The converter has thermal shutdown to prevent any damage from overheating. The TPS22919 is available in a standard SC-70 package characterized for operation over a junction temperature range of -40°C to +125°C.

ACHS-719x Linear Current Sensor ICs

Posted on by mixos

Broadcom’s ACHS-719x sensor ICs have a compact, surface mountable, SO-8 package that meets worldwide regulatory safety standards

The Broadcom ACHS-719x (±10 A to ±50 A) fully integrated Hall effect-based isolated linear current sensors are designed for AC or DC current sensing in industrial, commercial, and communications systems. Inside each ACHS-719x IC is a precise, low-offset, linear Hall circuit with a copper conduction path located near the surface of the die. Applied current flowing through this copper conduction path generates a magnetic field that the differential Hall sensors convert into a proportional voltage. Device accuracy is optimized across the operating ambient temperature through the close proximity of the magnetic signal to the Hall sensors. A precise, proportional voltage is provided by the low-offset, chopper-stabilized CMOS Hall IC, programmed for accuracy after packaging. The output of the device has a positive slope (>VOUT(Q)) when an increasing current flows through the primary copper conduction path (from pins 1 and 2 to pins 3 and 4), which is the path used for current sampling. The internal resistance of this conductive path is 0.7 mΩ typical, providing low power loss. The terminals of the conductive path are electrically isolated from the signal leads (pins 5 through 8). This performance is delivered in a compact, surface-mountable, SO-8 package that meets worldwide regulatory safety standards.

New Power Supply Provides Single and Dual Outputs with up to 35 V / 6 A per Output

Posted on by mixos

New R&S NGA100 Brings Linear Accuracy to The Basic Power Supply Class

Simply providing DC electricity is the purpose of a basic power supply, the piece of test equipment most commonly found on workbenches around the world. The R&S NGA100, a new series of basic power supplies from Rohde & Schwarz, goes beyond this requirement and brings a performance level and extra functions not usually associated with this instrument class.

Rohde & Schwarz continues to expand their range of basic power supplies with the new R&S NGA100 series. The R&S NGA100 is available in four models, providing a choice of single and dual outputs with up to 35 V / 6 A per output, or 100 V / 2 A per output. Single output models supply up to 40 W, dual output models up to 80 W power. The dual model outputs can be combined to provide up to 200 V or 12 A.

Rohde & Schwarz has implemented a linear design throughout the output circuits of the R&S NGA100 which significantly improves performance compared to the switched-mode circuits frequently found in basic power supplies. The resulting higher accuracy means engineers can be confident of supplying exactly the right power level without any need for an additional multi-meter. The standard level of read-back resolution, 1 mV / 100 µA, is enhanced for currents under 200 mA to a resolution of 1 µA, ideal to test low current levels typical for IoT applications in standby and sleep mode. The R&S NGA100 also has the necessary dynamic range for the power and current spikes from the same devices when switched to active mode.

While many basic power supplies only output maximum power within a very limited voltage/amperage range, the R&S FlexPower technology provides maximum power for a wide range of combinations, so that a single instrument can support many different applications. No matter which application, users benefit from the clear screen, intuitive user interface, and features like instantaneous statistical functions for maximum and minimum values for power, voltage and current, displayed directly on the screen.

Other features of the R&S NGA100 not commonly found in a basic power supply include logging voltage and current values for analysis, with up to 10 samples per second. For data export and remote control, Ethernet and USB are supported as standard, with optional WLAN and an external trigger with Digital I/O. Users can generate sequences of voltage/current settings at intervals down to 10 ms. The supplied power is not only low-distortion and low-noise, but thanks to the instrument’s remote sensing function, cable losses can even be compensated for. The correct level is at the input to the device under test, not at the output of the power supply.

The new R&S NGA100 power supply series is part of the R&S Essentials portfolio, and is available now from Rohde & Schwarz and selected distribution partners.

Firefly ROC-RK3566-PC Mini Computer Comes With HTPC Distro

Posted on by Abhishek Jadhav

ROC-RK3566-PC

We have recently seen several development boards integrated with the Rockchip SoC, including NanoPi R4S, Novasom M9, Tinker Board 2, and several others. However, we haven’t seen many boards built around the Rockchip RK3566 chip except the Pine’s Quartz64. To continue, the emergence of development boards powered by the RK3566 has sparked the launch of the Firefly ROC-RK3566-PC mini-computer.

Firefly has expanded its long list of mini-computers with this newly launched high-performance, low-power single-board computer that gets a quad-core 64-bit Cortex-A55 processor, clocked up to 1.8 GHz frequency along with the Mali-G52 GPU. With the integrated, powerful Rockchip SoC, the mini-computer opens the door to many capabilities. The developer can build many exciting projects with this SBC that supports 8 GB RAM, just like the Raspberry Pi 4 model.

ROC-RK3566-PC Specs

The dedicated GPU, Mali-52, supports all modern graphics APIs like OpenGL ES 3.2, Vulkan 1.0, and OpenCL 2.0, and Renderscript. However, this might not be the best option out there as the HiKey 960 gets the Mali-G72 GPU. With the high-performance VPU, the mini-computer is set to achieve 4K 60fps H.265/H.264/VP9 video decoding and 1080P 100fps H.265/ H.264 video encoding.

For those developers looking for extra storage rather than the available 32GB / 64GB / 128GB eMMC, they can use the optional M.2 PCIe 2.0 interface to expand with a 2242 NVMe SSD. Adding more to this, the manufacturer has also provided the board with a TF-Card slot to upgrade the storage. Even with minimalistic design, the SBC supports Gigabit Ethernet along with some wireless connectivity of Wi-Fi 802.11 a/b/g/n and Bluetooth 5.0.

ROC-RK3566-PC Storage

The mini-computer is slightly bigger (90.0 mm x 60.0 mm) than the Raspberry Pi 4 Model B (85.0 mm x 56.0 mm), but that does not affect the portability much. With the support for Android 11.0, Ubuntu 18.04, Buildroot + QT, Station OS, the SBC gives the user choice of experimenting with building applications. The manufacturer has introduced the board with a rich set of interfaces allowing you to take advantage of HDMI2.0, USB3.0, USB2.0, MIPI DSI, MIPI CSI, I2C, SPI, UART, and many more. To power the SBC, you get a Type-C port, which is the developer’s most asked option.

“A complete SDK, development documents, examples, technology documents, tutorials, and other resources are provided for the users to make a further customization.”

However, this information is currently not released and can be expected soon. More information about the Firefly ROC-RK3566-PC is available on the product page with no pricing details.

Posted on by Tope Oluyemi

Do you want to make your Arduino or Raspberry Pi wirelessly send messages? Think no more, Axon is the answer. With just only two wires (TX and RX) your microcontroller can talk to a Linux computer thousands of Km away, or maybe track the logs of your Raspberry Pi located in a 400m skyscraper. This concept offers endless possibilities. Speak about the concept of this device, the company says:

“Its concept is quite simple; the idea is to enable IoT technology on any device that speaks serial, connect it to the internet, bring it to life and make lots of cool things happen.”

Measuring at just 25x30mm, Axon is a small and versatile IoT board that easily integrated into any project with just two wires, aka UART (TX and RX). Axon works by utilizing the wireless freedom of WiFi, and incorporates it with Axon Cloud which enables an online serial monitor and database storage for your UART serial data.

The board features a switch so that you can select between USB-C or header pins. This feature comes in handy when you have two different sources of data working simultaneously. You can choose who you want to listen to. Axon offers the option of operating it as a stand-alone device, or you can attach it to an intelligent device. For clarity, you can place several battery-powered Axon modules in remote locations to gather data such as temperature, humidity, light, or liquid level, and when operating as a stand-alone device, Axon simply sends sensor data to Axon Cloud, where you can use the terminal app or database for serial data storage. Axon Cloud is a new social network for IoT devices. When an Axon is connected to an intelligent device like a computer, Arduino, or Raspberry Pi, it utilizes serial communication. It works by the intelligent device sending data through the serial interface to Axon module to be transmitted to other devices over the cloud, and also Axon receiving wireless data from other devices, and then sending the data through the serial interface to the intelligent device.

The Axon module interfaces to a host device such as a microcontroller or computer via a logic-level asynchronous serial port. These host devices make use of a UART for serial communication. The microcontrollers attached to Axon processes the data received by the module, and then monitors or controls remote devices by sending messages via Axon Cloud. You can also use external microcontrollers such as Arduino or Raspberry Pi, sockets, and breadboards for prototyping. Axon is easy to use with any microcontroller or serial-speaking device to send and receive messages over the cloud. You can swiftly setup your Axon project and get it running in less than 2 min. The board features an intriguing portal page that enables you to enter your Authentication key to connect WiFi and establish a secure encrypted connection. The LoRa module enables you to turn your Axon board into a fully operational IoT LoRa  1-channel gateway. You will be able to send & receive data from remote areas where WiFi or LTE is not available. This offers a host of possibilities for cool long-range projects.

Available also is Openspace, which is the first social network platform for IoT devices, where you can share your real-time data with other Axon-connected devices. The platform enables you to share & gather data from other users so you can monitor or control other people’s devices using Axon. The platform works by sharing your device public key created on the platform so other people can subscribe to your device, the data is then encrypted and sent over WiFi through their servers until it reaches the destination in just a few seconds.

Olimex RP2040-PICO-PC Computer Made with RP2040-Py module compatible with Raspberry Pi Pico

Posted on by Emmanuel Odunlade

Olimex has manufactured the first prototypes of their new RP2040-PICO-PC designed to create a small Raspberry Pi RP2040 computer with HDMI/DVI video output.

“It’s a small baseboard for RP2040-PICO, the $4 Cortex-M0+ processor-based module developed by Raspberry Pi foundation.”

the company writes.

With HDMI video output, 2MB SPI flash or a memory card for storage, speakers connected to the audio jack, keyboard, and mouse, one can use the RP2040-PICO-PC board as a small computer, though it won’t be able to run typical OS like Linux and it’s kind.

Key features and specifications of the RP2040-PICO-PC small computer board include:

  • Supports Raspberry Pi Pico board
  • Has a micro SD card for storage
  • An HDMI port with DVI signal to connect to monitor (no audio through this interface)
  • 3.5mm audio jack
  • UEXT connector with UART, SPI, I2C, 3.3V, and GND
  • Grove compatible JST2.0 4-pin header with I2C plus power signals
  • Debug connector for Serial adapter
  • 1x Reset button
  • Power Supply: 5V via the micro USB port located just below the RP2040 PICO module
  • LiPo battery for handheld operation and power backup
  • Dimension: Small size

The Bulgarian company also designed their own RP2040-PICO module since it was not easy getting enough Raspberry Pi Pico boards for production. They had a reel of Raspberry Pi RP2040 processors, so they could easily come up with an RP2040-Py module compatible with Raspberry Pi Pico.

The RP2040-Py is the same as the original RP2040-PICO module but with some improvements:

  • An extra USB micro connector on the right hand for power
  • An extra uUEXT connector located at the bottom of the board
  • One extra reset
  • An optional JTAG USB debugger
  • DC-DC power supply with 3.3V up to 2A

Every other functional feature of the RP2040-Py and the RP2040-PICO module are exactly the same (Raspberry Pi SoC,  2MP SPI flash, I/O headers, and Micro USB connector).

Both the RP2040-PICO-PC and RP2040-Py would be up for sale in early May. The RP2040-PICO-PC including the original RP2040-PICO board with soldered headers will sell for 12 Euros, while the RP2040-Py module will be available in three different models namely:

  • Basic (5 Euros) – Just like the Raspberry Pi Pico board but with higher current DCDC power supply, reset button and uUEXT connector.
  • Basic+ (8 Euros) – This is the Basic model plus soldered headers and additional micro USB for power
  • Debug (19 Euros) – Same as the Basic+ model but with populated JTAG parts for debugging.

Further details can be found in the announcement on Olimex blog.
