I have a sensor module, which is switched with a P-channel FET as a high side switch. When the module is switched off after operation, I measured an unexpected 1,3V on the switched line (OUTPUT), which discarges in approx. 15sec. Now I'm sure it is "coming back" from the sensor, because if the sensor is not connected, I measure 0V instantly after FET switch off.
Would it do any harm if I connect e.g. a 100k resistor between the OUTPUT line and GND?
(I think it would discharge faster any voltage "left" in the sensor module.)
Thanks in advance.
