If TLE9210x is in passive mode, why PWM3 pin is pulled down by an internal open drain when VS overvoltage is detected?
This is a signalization of overvoltage to the uC which is controlling the device. When the uC sees PWM3 pin is pulled down when TLE92104 is in passive mode, the uC knows that there is VS overvoltage detected, and LSs are turned ON.
