GaN based half bridge board with gate driver
Hello,I am looking for GaN based half bridges or full bridges evaluation board with gate driver for 250-400V and 3.3kW power rating for Dual active bridge DC-DC converter.Kindly suggest evaluation/ development board for the same Thanks & RegardsAbhis...
Stacking TVS Diodes onto Resistors for Space Saving
Hello we have a need to string the SMAJ58A-TR TVS Diodes with some chip resistors in parallel and I'm wondering if we could physically stack the diodes on top of the resistors due to limited board space. If so, what resistor package would be ideal an...
BTA26-80BWRG
Hello, I have questions about a project we developed a long time ago. I will put the schematic below. We are using the BTA26-800BWRG (U8 and U9) in the schematic to parallel two inductors. The voltage applied to these two inductors is an ultrasonic s...
viper22a short circuit protection problem
Hello, I use viper22A for 220VAC to 14VDC-1A PSU. When I shorted output, around 3A current flows from Ampermeter. Viper22A datasheet explain that if output is short circuit no feedback will come from optocoupler, FB pin voltage will be 0V (my measure...
About the Safe Operating Area (SOA) described in the SiC MOSFET datasheet
I am a power electronics engineer. I would like to know if the Safe Operating Area (SOA) specified in the datasheet for your company's SiC MOSFET SCT040W65G3-4AG is a guaranteed value.
Resolved! Need help with L99615 Steval communication
Hello,I am currently working with the STEVAL-L99615C evaluation kit and the Nucleo G071RB microcontroller board. My goal is to set up a LabVIEW program that can:1. Adjust the output voltages of power supplies to simulate real battery cells.2. Read da...
BMS using AEK-POW-BMS63EN
Hi,New to the community here.I am new to using this BMS evaluation board AEK-POW-BMS63EN. I want to connect a battery pack to this and an external microcontroller to receive the digital data and do something with it.So a battery pack as input to this...
VNQ9025AJ not supporting the current and thermal protection not working
Hello ST Community,I'm working on a project that uses the VNQ9025AJ, a quad-channel high-side driver, to manage the power supply in a car—primarily for powering fans and pumps. We are using 12V as VCC.According to the datasheet, each channel supports...
Resolved! Looking for a low Iq (e.g. 1uA) eFuse
Hello,I looked through the data sheets of multiple efuses and cannot really find reliable values of Iq (quiescent current) values (somtimes only leakage for certain pins is given). Even the product selector does not show any listings of Iq. Every oth...
L9963E addressing issue.
I having issue addressing L9963E when the device is already awake. Currently my team is working on developing a BMS using two L9963E in a daisy chain configuration. In some instances, we may have to reset our micro controller(eg: Soft Reset, WDT rese...
