(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; see Figure 25.

(3) VID refers to the differential voltage at the comparator inputs.
(4) Pulling the open-drain output to the range of 2.7 V to 18 V is permissible, regardless of VS.
(5) The comparator response time specified is the interval between the input step function and the instant when the output crosses 1.4 V.
(6) The RESET input has an internal 2-MΩ (typical) pulldown. Leaving RESET open results in a low state, with transparent comparator operation.

7.7 Electrical Characteristics: General

at TA = 25°C, VS = 12 V, VCM = 12 V, VSENSE = 100 mV, RL = 10 kΩ to GND, RPULL-UP = 5.1 kΩ connected from CMPOUT to VS, and CMPIN = 1 V (unless otherwise noted)
GENERAL PARAMETERS CONDITIONS MIN TYP MAX UNIT
POWER SUPPLY
IQ Quiescent current VOUT = 2 V 1350 1800 μA
VSENSE = 0 mV, TA = –40°C to 125°C 1850 μA
Comparator power-on reset threshold(1) 1.5 V
(1) The INA20x-Q1 devices power up with the comparator in a defined reset state as long as the RESET pin 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.
