(1) The INA206, INA207, and INA208 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 will assume 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.
