Please reply my question regarding L9369 GIO
I am writing because I have a question about the L9369 chip. The second case of above table ( SPI_GIOx_HSCtrl == 0 and SPI_Off_Giox == 1) , Output is set to HIGH. I'm curious why GIOx Output is HIGH when SPI_GIOx_HSCtrl is 0. Thank you.
Do you have a solution for wBMS?
Hi~ I am curious about the solution which referred to the wBMS I heard that you have BMS solution SOC. But I haven't heard about the wBMS. If you have, please let me know it Many thanks BRs Daniel Lim
Resolved! LED1202QTR
Hello ST Team,We are observing that LEDs are minor glowing, during turn off condition due to leakage current. As per our application we are not not using any PWM configuration for LEDs. We are just making LEDs turn ON/OFF as per application requireme...
