(1) The INA203, INA204, and INA205 are 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.
