IRLR7843 Datasheet

High Accuracy Adjustable Overvoltage and Overcurrent Protectors using MAX17561

If you need safe power to run your project, then this circuit is a possible solution for you. This project provides protection to your system device against over-current, over-voltage, under-voltage, thermal overload, and reverse current flow control to the system device. Basically, this project can play a key role between the power supply and the sensitive system device, where the system device will be protected against the above conditions. When there is a change other than the set parameters the circuit will disable the output and go in retry mode, until the condition is as per the set value. The project is built using MAX17561 chip. Refer to the datasheet to get further information. Refer to the schematic shown below and have look at some of the panorama of the project explained below.

Important Features:

Adjustable overvoltage protection range is between 6V and 36V
Adjustable undervoltage protection range is between 4.5V and 24V
Overvoltage-lockout (OVLO) thresholds are set using external resistors R1 and R7
Undervoltage-lockout (UVLO) thresholds are set using external resistors R2 and R8
Programmable Forward-Current Limit: 0.7A to 4.2A (±15% Accuracy) is set using R9 (R9 13K = Approx. 1Amp)
Reverse Current Flow Control Input
Thermal Overload Protection
Dual Enable Inputs: EN and High Voltage HVEN
Fault Indicator Output. FLAG goes low when the fault duration exceeds the blanking time, reverse current is detected, the thermal-shutdown mode is active, OVLO threshold is reached, or SET-Current is connected to GND.
Reverse-Current Enable Input. Open the Jumper J3 enables reverse-current flow protection. Close the Jumper J3 (RIEN to logic-high) to disable the reverse-current flow protection
EN: Close the Jumper J2 to enable the input (Active-High Enable Input)
HVEN: Close the Jumper J1 to activate HVEN High voltage Enable (36V Capable Active-Low Enable Input)
PCB dimensions: 70.01 x 51.28 mm

Switch Control

There are two independent enable inputs (HVEN and EN) for the devices. HVEN is a high-voltage-capable input. Toggle HVEN or EN to reset the fault condition once a short circuit is detected and the devices shut down.

Jumper J1 Close, Jumper J2 Open >> Switch Status ON
Jumper J1 Close, Jumper J2 Close>> Switch Status ON
Jumper J1 Open, Jumper J2 Close>> Switch Status ON
Jumper J1 Open, Jumper J2 Open>> Switch Status OFF
Jumper J3: Open enables reverse-current flow protection. Close the Jumper J3 (RIEN to logic-high) to disable the reverse-current flow protection

Adjusting Parameters

Refer to the figure which explains the formula to set the overvoltage, Under voltage, and Load Curren:

Testing the board

Perform the following steps to test the project, Close Jumper 1 and Jumper 2, connect the voltmeter on output, Connect 5V DC power supply to VCC and GND pin of CN3. Use another variable power supply, adjust the voltage to 19.5V and connect this power supply to input CN1, verify that output is 19.5V DC and Flag pin is high. Gradually increase the DC power supply voltage and verify that OUT voltage goes down and Flag pin is low when input reached approximately 33V. Gradually decrease voltage on the DC power supply and verify that OUT comes back and Flag pin is high again when the input reaches approximately 32V. So the safe range of voltage input is 19.5V to 32V with Load Capacity 1 A. This project can work with a single power supply if Fault/Flag information is not required.

Default internal factory-pre-set internal OVLO threshold is 33V (typ.) and the pre-set internal UVLO threshold is 19.2V (typ.) The current-limit protection is set using R9 to 1A, but current limit protection is programable up to 4.2A, once current reaches the threshold, the MAX17561 turns off the output after the 20.7ms (typ) blanking time and stays off during the retry period.

Auto retry Current Limit

When the current threshold is reached, the tBLANK timer begins counting. The FLAG asserts if the overcurrent condition is present for tBLANK. The timer resets if the overcurrent condition disappears before tBLANK has elapsed. A retry time delay, tRETRY, is started immediately after tBLANK has elapsed and during tRETRY time, the FETs are off. At the end of tRETRY, the FETs are turned on again. If the fault still exists, the cycle is repeated and the FLAG stays low. When the fault is removed, the FETs stay on. If the die temperature exceeds +150NC (typ) due to self-heating, the MAX17561 enables thermal shutdown until the die temperature drops by approximately 30NC . The autoretry feature reduces the system power in case of overcurrent or short-circuit conditions. During tBLANK time, when the switch is on, the supply current is held at the current current limit. During tRETRY time, when the switch is off, there is no current through the switch. Thus, the output current is much less than the programmed current limit. With a 20.7ms (typ) tBLANK and 600ms (typ) tRETRY, the duty cycle is 3.3%, resulting in a 96.7% power savings.

Reverse-Current Block Enable (RIEN)

This feature enables reverse-current protection and disables reverse-current flow from OUT to IN. The reverse-current block feature is useful in applications with inductive loads.

“EnerCera” Battery Series helps develop Maintenance-Free IoT Devices

Posted on 11 March, 202111 March, 2021 by mixos

NGK INSULATORS, LTD., announced that it has commenced collaboration with Renesas Electronics Corporation, on promoting the widespread adoption of maintenance-free IoT devices. As the first phase of collaboration, NGK and Renesas jointly-developed a reference design for a wireless air quality sensing system that will contribute to the realization of a decarbonized society. The system was developed by combining NGK’s EnerCera battery series and Renesas’ RE Family of ultra-low power microcontrollers (MCUs).

Data collection and utilization are considered to be the most effective means of realizing a productive life or addressing social issues. Meanwhile, actions to achieve the decarbonization of society have been gathering momentum on a global basis. For example, Japan and many other countries around the world have adopted the goal of achieving net zero greenhouse gas emissions by 2050. Therefore, these countries will be required to reduce their power consumption even as they deploy numerous IoT devices for data collection purposes. To realize such a society, there is a need to develop maintenance-free IoT devices that can be powered by trace amounts of electric power obtainable from energy sources in the environment, such as peripheral light, heat, and vibration energy. It also requires for a device that do not require battery replacement.

1. Can be charged efficiently with tiny power from Solar Cell. 2. Can output high power to drive wireless communication IC etc. 3. Can drive device stably even during the night.

EnerCera battery series is a lithium-ion rechargeable battery featuring a high capacity, low resistance, and long life despite having a compact, ultra-thin body. EnerCera battery series is ideal as a power source for maintenance-free IoT devices, since it can efficiently charge itself with a weak current and output an intermittent large current to drive functions such as sensing and communication. To power a device with the electric power stored in the battery, an MCU that links the battery with sensor ICs, communication ICs, and other components is needed. For this reason, NGK has developed a reference design for promoting the widespread adoption of maintenance-free IoT devices, together with Renesas’ RE Family MCUs that realize industry-leading ultra-low power consumption.

“We are confident that the combination of NGK’s battery technology and Renesas’ ultra-low power consumption technology will accelerate the widespread adoption of battery maintenance-free IoT devices,” said Makoto Mizokuchi, Head of Low Power Products Department at Renesas.

“I’m convinced that NGK’s collaboration with Renesas will promote the development of maintenance-free IoT devices, thereby helping to solve social issues while realizing a decarbonized society.” said Iwao Ohwada, Vice President and General Manager, Advanced Device Components Div., Electronics Business Group at NGK.

As the first phase of collaboration, NGK and Renesas jointly-developed a reference design for wireless outdoor air quality sensing systems powered by solar cells. Monitoring pollution levels in outdoor air provides valuable insights on the associated health effects from elevated levels. Conventional sensing systems have presented problems such as requiring power cables due to their large power consumption and thus being subject to restrictions on sites where they could be installed. The combination of ultra-low power RE MCUs and low resistance, high-capacity EnerCera batteries will enable constant measurement of outdoor air quality indexes at all times, even with only trace amounts of intermittent electric power obtainable from the solar cells. This will allow monitoring of the degree of atmospheric pollution without having to devote time and effort to power cable wiring and battery replacement. The system can also support long-distance radio communications such as low-power wide-area (LPWA) network technologies, enabling centralized management of measurements from numerous sensors in the field.

Not only for environmental monitoring but also a variety of other fields, NGK and Renesas will continue to jointly-develop reference designs to realize the widespread adoption of maintenance-free IoT devices that combine the EnerCera battery series and RE Family MCUs.

Posted on 11 March, 2021 by Abhishek Jadhav

USB has evolved over the last few years with the latest launch of the ST’s standalone VBUS-based controller. To help build a compact and efficient power adapter that provides up to 27W with zero-power operation when no cable is connected, STMicroelectronics has unveiled a new reference design with Programmable Power Supply (PPS). All new ST’s STEVAL-USBPD27S solution introduced has the PPS capabilities through three-stage architecture. Apart from the power supply section and the power control stage is the digital control stage that is built around the STM32G071KB Arm Cortex-M0+ MCU that controls the USB Type-C connector and the Power Delivery 3.0 communication protocol.

One of the key technical benefits lies in the specific algorithm running on the MCU that can control the VBUS on the secondary side, and is “compliant to USB Type-C and Power Delivery and PPS specifications”. The onboard flyback converter combines a high-performance, low-voltage PWM controller chip on the same package. For Type-C port protection, the solution is provided with a single chip solution – TCPP01-M12 – that ensures robustness and protection.

As an MCU-based solution, the reference design gives users extra flexibility to implement additional customized application layers and to incorporate ongoing improvements as the USB Power Delivery standard evolves.

The STEVAL-USBPD27S is USB power delivery 3.0 compliant with a wide range of input voltages. This is capable of delivering:

Two fixed PDOs: 5V@5A, 9V@3A
Two APDOs (PPS): 5VProg@5A, 9VProg@3A

This compact form factor of 59 x 35 x 21mm in size and 10.2 W/inch³ that has a standard output power of 27 W. With the STCH03 PWM controller offers several advantages to the solution featuring “high-voltage start-up circuitry, primary-side constant-current output regulation, and advanced power management”.

For more information on the reference design to accelerate the design of a power adapter that delivers an output of up to 27W, visit the press release by the company. The ST’s STEVAL-USBPD27S is expected to be sold at a price of $95.00.

TMCS1107 420 V Isolated Hall-Effect Current Sensor

Posted on 9 March, 20219 March, 2021 by mixos

Texas Instruments’ sensor is optimized for high accuracy and temperature stability

Texas Instruments‘ TMCS1107 is a galvanically isolated Hall-effect current sensor capable of DC or AC current measurement with high accuracy, excellent linearity, and temperature stability. A low-drift, temperature compensated signal chain provides <3% full-scale error across the device temperature range. The input current flows through an internal 1.8 mΩ conductor that generates a magnetic field measured by an integrated Hall-effect sensor. This structure eliminates external concentrators and simplifies design. Low conductor resistance minimizes power loss and thermal dissipation. Inherent galvanic insulation provides a 420 V lifetime working voltage and 3 kV_RMS basic isolation between the current path and circuitry.

Integrated electrical shielding enables excellent common-mode rejection and transient immunity. The output voltage is proportional to the input current with multiple sensitivity options. Fixed sensitivity allows the TMCS1107 to operate from a single 3 V to 5.5 V power supply, eliminates ratiometry errors, and improves supply noise rejection. The current polarity is considered positive when flowing into the positive input pin. Unidirectional and bidirectional sensing variants are available. The TMCS1107 draws a maximum supply current of 6 mA and the sensitivity options are specified over the operating temperature range of -40°C to +125°C.
