LM7481-Q1: BATT_MON when Reverse Battery

Part Number: LM7481-Q1
Other Parts Discussed in Thread: LM74800EVM-CD


Does it have negative voltage at OV pin(or BATT_MON) when Reverse Battery ?  I did the test and found there will be a negative voltage at OV pin(or BATT_MON). Can you explain it? We would like to use the pin to MCU ADC for the battery monitor, but the negative voltage is not acceptable. Do you have any idea?
