The INA203-Q1 is designed to power-up with the comparator in a defined reset state as long as CMP1 RESET is open or grounded.

The comparator will be in reset as long as the power supply is below the voltage shown here. The comparator assumes a state based

on the comparator input above this supply voltage. If CMP1 RESET is high at power-up, the comparator output comes up high and

requires a reset to assume a low state, if appropriate.
