Hello!
I have connected the output of TLV3501 comparator to the GPIO pin of a 3.3V microcontroller. The GPIO is configured to interrput to falling edge. Irrespective of defining the GPIO pin's pull-up or pull-down conditions, the GPIO pin voltage remains 2V, which is causing a DC up-shift in the TLV3501's output. Does this mean that TLV3501 has damaged the GPIO pin of the iC?
The following cares have been taken:
1. Common Ground potential to both uC and TLV3501
2. Introducing series resistor at comparator input
