I ran into some problems with the E-L9826 low side driver.
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...
L9963E cell balancing
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...
Resolved! STWBC86 operating frequency
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...
Resolved! L7987 in LDO when VIN < VOUT programmed
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...

Resolved! STEVAL-10MLPVCB Code
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...
L9825 SPI INTERFACE TIMING related concerns
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...
