(1) Hysteresis refers to the threshold (the threshold specification applies to a rising edge of a noninverting input) of a falling edge on the noninverting input of the comparator; refer to Figure 1.

(1) The INA200, INA201, and INA202 are designed to power-up with the comparator in a defined reset state as long as RESET is open or grounded. The comparator is 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 RESET is high at power-up, the comparator output comes up high and requires a reset to assume a low state, if appropriate.
