Discuss power management solutions. Ask questions and find answers on voltage configurations, short circuit protection, and programming.
Here is my hardware design. The output with load goes high during chip reset. When I cancel the reset, the output immediately goes low before I have done any control. I turn the output on or off again with no effect and at this point the diagnostic d...
Hello.I have a problem with this IC. I can read cell voltages perfectly. but when I initiate cell balancing on selected cells, its not happening. for that I follow these steps:1- I enable cells by writing on 0X1C Register.2- I set UV threshold by wri...
Does the charger IC ever operate outside of the specified TX FREQ MAX and TX FREQ MIN limits?For example, if the limits are set to 100kHz and 148kHz and the charger is operating at either limit, would FSK cause it to change the frequency below this v...
HiI am working on an application with wide VIN from 6V-60V and the target VOUT is 15V 3A max.When VIN > 16V, L7987 should fit my application. Problem is that when VIN drops below 16V, eDesignSuite reports an error so simulation is not possible. It st...
Hello ST community,We are working on a 15kW Rectifier module for EV charging application. This module contains 15kW Vienna rectifier and 12kW DC DC converter, input voltage: 3 phase 415V, output voltage: 40V-120V. For this requirement, we are explori...
Hello ST Team, Greeting from Uniglobus, is the child R&D Electronics company of Polycab India limited My self Grishma Bhatt, I am Power Electronics Design Engineer We would like to start a new product 3.3KVA Single phase non isolated solar on grid In...
Hi,I am building a 3L Buck Converter with MPPT tracking, using the STM32G474CBT6.The STEVAL-10MLPVCB has a very similar concept to what I want to achieve, I based my MCU choice and other details on it.Is it possible to obtain the source code / CubeID...
I have following three concerns related to SPI interface timing of L9825 low side driver IC. Please refer the image below. 1. Do we really need to toggle the clock signal within 100ns after NCS changed from High to low. If this 100ns is exceeded what...
I get an error message when I try to connect with the STEVAL-WLC38RX evaluation board using STSW-WPSTUDIO. I am using v2.7.2 of WP Studio. See error message attached.
