6.6 Electrical Characteristics: Comparator

At TA = 25°C, VS = 12 V, VCM = 12 V, VSENSE = 100 mV, RL = 10 kΩ to GND, and RPULL-UP = 5.1 kΩ connected from CMPOUT to

VS, unless otherwise noted.

(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.

(2)

Specified by design.

(3)

VID refers to the differential voltage at the comparator inputs.

(4)

Open-drain output can be pulled to the range of 2.7 to 18 V, 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 M

Ω (typical) pull-down. Leaving RESET open results in a LOW state, with transparent comparator

operation.

6.7 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.

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.
