mosfet driver input exceeds absolute maximum ratings #4

Open Stapelzeiger opened 9 years ago

When the 15V power supply is shut off, the inputs of the mosfet driver are still driven by the STM32.

can that lead to MOSFET destruction ?

no, but it might damage the mosfet driver or the STM32. Currently our workaround is to use open-drain output & pullup on the STM32.
