Energy harvesting PMIC from Nexperia includes MPPT tracking

Posted on by mixos

Nexperia, the expert in essential semiconductors, today announced an expansion to its range of Power ICs with Energy Harvesting solutions to simplify and enhance the performance of low-power internet of things (IoT) and other embedded applications. The NEH2000BY is a high-performance power management integrated circuit (PMIC) which recharges a battery or storage capacitor using energy harvested from ambient sources, such as light (which can be harvested using a photovoltaic cell). As a result, Nexperia’s NEH2000BY will enable the development of electronic devices that are self-powered, smaller, and environmentally friendly. Furthermore, this energy harvesting solution can help mitigate the environmental impact of the billions of batteries produced and discarded each year.

Nexperia’s NEH2000BY PMIC makes it much easier to design energy harvesting solutions which can be up to 20x smaller than other competing offerings and do not require manual optimization for individual applications. In addition, the PMIC was designed without inductors, simplifying PCB design, and significantly reducing overall BOM and board size, with a 12 mm² assembly area.

To achieve the highest conversion efficiency, energy harvesting solutions must be able to adapt as the ambient energy source fluctuates. The NEH2000BY performs Maximum Power Point Tracking (MPPT), an adaptive algorithm to optimize how it transfers harvested energy and to achieve optimum average conversion efficiency by up to 80%. This unique MPPT algorithm combines speed with accuracy, allowing the PMIC to adapt to environmental changes in less than a second. This is significantly faster than any other currently available solution and maximizes the amount of energy harvested over the course of a day, vastly expanding the number of application areas. Furthermore, due to its self-optimization functionality and ability to operate autonomously without the requirement for pre-programming, the NEH2000BY makes it easier for designers to power devices with ambient energy.

Nexperia’s energy harvesting solutions enable economical energy harvesting from various ambient sources in applications consuming up to several milliwatts of power, including wireless IoT nodes, wearable smart tags, and electronic shelf labels.

Dan Jensen, General Manager Business Group Analog & Logic IC’s at Nexperia adds,

“The NEH2000BY’s cost-efficient, user-friendly, and compact nature will allow the adoption of energy harvesting in a larger range of use cases. By eliminating the requirement to change batteries in these applications, NEH2000BY will significantly reduce the amount of hazardous waste produced, with enormous environmental benefits.”

The NEH2000BY is available in a 16-lead, 3 mm × 3 mm QFN package and operates between -40°C and +85°C.

Highly stable digital MEMS gyroscope for dynamic applications

Posted on by mixos

TDK Corp. introduces the Tronics Gypro4300, a highly stable and vibration-resistant digital MEMS gyroscope for dynamic applications. The gyro is also ideally equipped for use in vehicles.

The Tronics Gypro4300 features an input measurement range of ±300 °/s, a bandwidth of 200 Hz and a latency of 1 ms, and has a closed-loop architecture that ensures high linearity and stability in dynamic environments. The Gypro4300 is the first product in the new Gypro4000 high-performance MEMS digital gyroscope platform, which complements the AXO300 digital closed-loop accelerometer platform.

With an excellent bias instability of only 0.5 °/h as a typical value (2 °/h maximum) and an ARW (Angular Random Walk) of 0.1 °/√h, the Gypro4300 offers a miniaturised, digital MEMS high-performance gyroscope with a low SWaP (Size, Weight and Power) value, paving the way for a new generation of high-precision positioning, navigation and stabilisation functions in dynamic applications such as rail vehicles, land vehicles, VTOL (Vertical Take-Off and Landing) aircraft and UAV (Unmanned Aerial Vehicles), marine and underwater systems, drilling and surveying instruments.

Compact, robust gyroscope for use in high-vibration environments

The Gypro4300’s closed-loop architecture provides high vibration damping of 0.5 °/h/g² in harsh conditions. The gyroscopes are housed in a hermetically sealed, ceramic J-lead miniature enclosure that offers long operating and storage life, as well as high compliance with the stringent temperature cycling requirements of critical applications. They feature hard-coded electronics with a 24-bit SPI digital interface for rapid integration into INS (Inertial Navigation Systems), IMU (Inertial Measurement Units) and AHRS (Attitude and Heading Reference Systems). To minimize mechanical coupling in multi-axis applications, the Gypro4300 is available for three frequency ranges.

Thanks to its miniature package and low power consumption, Gypro4300 offers a digital, low-cost and low-power alternative to bulky, expensive and power-hungry solutions such as DTG (Dynamically Tuned Gyros) and FOG (Fiber Optical Gyroscopes). Thanks to its solid-state architecture, which reduces the number of internal components and system complexity, the Gypro4300 has an MTBF of more than 1,000,000 hours, which is ten times more than established DTG and FOG solutions with similar performance. In addition, the built-in self-test provides both an initial check of the sensor’s integrity and a continuous functional test during operation.

The Tronics Gypro4300 gyros are ideally complemented by the AXO300 high-performance digital accelerometers, which use the same SMD J-lead ceramic package and digital interface to enable cost-effective integration, mounting and board reliability, even in rapidly changing temperature conditions.

The Gypro4300 is available for sample and customer evaluation directly from Tronics or through specialised distribution channels such as TEXIM in Europe. Rapid evaluation of the sensors can also be done with an Arduino-based evaluation kit that offers built-in test functions such as reading and recording outputs, recalibration and digital self-testing.

Sequent Microsystem’s 6-in-1 LCD Adapter HAT for Raspberry Pi

Posted on by Rakesh Kumar, Ph.D.

For standalone Raspberry Pi projects, Sequent Microsystems developed an LCD display adapter with a rotary encoder and 6 switches. The software has drivers for scrolling messages of up to 256 characters. The speed of scrolling can be changed from the command line. The messages can be played just once or over and over again in a loop.

Video

LCD Display Adapter Kit for Raspberry Pi:

The HDMI port on the Raspberry Pi can be used to drive a monitor or a TV. However, the majority of embedded systems only need to display a small amount of data. The ability to interact locally with the Pi and show a few lines of text may be really useful. Both 1602 and 2004 displays with monochrome or RGB backlit can be brought together. The RGB displays use 18 pins, while the 16-pin connector for monochrome displays. All six possible combinations can be inserted into the same 18-pin header and controlled from the same interface.

Monochrome or RGB backlit display connector

Universal, 6-in-1 Display Adapter HAT Specification:

Block diagram

LCD Display Adapter PCB Layout

The 6-in-1 Display Adapter HAT accommodates 2004 and 1602 displays with monochrome or RGD backlighting.

  • I/O Interface: The Display Adapter plugs into the Raspberry Pi’s GPIO connector. It only uses the I2C port to communicate with the Pi, so the other 26 GPIO pins can be used for other things. It can be put on top of any HAT that can be stacked.
  • Microprocessor: The display adapter includes a 32-bit STM32G030 microcontroller (up to 64MHz). It has two functions: First, it reads the state of the pushbuttons and the rotary encoder and reports it to the Raspberry Pi. Second, it implements commands received from the Raspberry Pi on the display adapter. The adaptor can show flashing, scrolling, or static messages.
  • Software: Python, Node-RED, and the command line are all included.
  • Misc: 1 x Rotary encoder. (The easiest way to move through multiple menus, show input values, and control outputs is to turn the rotary encoder)
    6 x Pushbuttons.
  • There are 2 types of standard tiny LCD displays:
    • 2 lines with 16 characters each (LCD1602) measure about 80mm x 36mm.
    • 4 lines with 20 characters (LCD2004). The 77 x 47mm and 98 x 60mm sizes of the 2004 display are available.

LCD1602 Display Adapter Hat

The 1602 LCD Display comes in different colors and has two lines of 16 characters each.  It comes without a connector or with a male connector already soldered with monochrome or RGB backlighting.

LCD Adapter with 1602 Display

LCD 1602 Display Adapter

If 16 characters and two lines are enough for an application, the groves on the side of the PCB are taken out and a rotary encoder is the soldered and top row of 6 pushbuttons. The adapter has 19mm standoffs and can be put on top of any other Raspberry Pi I/O card that can be stacked.

LCD Adapter for 1602 Display with Rotary Encoder and Six Pusp Buttons

LCD2004 Display Adapter HAT

The 2004 LCD Display has four lines of 20 characters each and comes in different colors. It comes without a connector or with a male connector already soldered with monochrome or RGB backlighting.

To use the display adapter with 20 characters and 4 lines displays, a rotary encoder is soldered, and the 6 pushbuttons are provided on the bottom row.

Components:

  • The surface mount components on a printed circuit board are all put together. Installed and tested microprocessor firmware.
  • 2×20 Male-Female Raspberry Pi Tall GPIO header.
  • Mounting hardware: brass standoffs, nuts, and screws. The adapter is installed using the 19mm standoffs on top of Raspberry Pi. In the case of the female header for the LCD display the display is secured with the 11mm standoffs.
  • Rotary Encoder and 6 pushbutton switches.
  • 1 x 18 Male and Female Pin Headers.

Detailed assembly of the LCD Display Adapter Kit is available on the product page.
