3 Description

The INA200, INA201, and INA202 devices are high-

side current-shunt monitors with voltage output and

integrated comparator. The INA20x devices can

sense

drops

across

shunts

at

common-mode

voltages from –16 V to 80 V. The INA20x series is

available with three output voltage scales: 20 V/V, 50

V/V, and 100 V/V, with a bandwidth up to 500-kHz.

The

INA200,

INA201,

and

INA202

devices

incorporate an open-drain comparator and internal

reference

providing

a

0.6-V

threshold.

External

dividers set the current trip point. The comparator

includes a latching capability, that can be made

transparent by grounding (or leaving open) the

RESET pin.

The INA200, INA201, and INA202 devices operate

from a single 2.7-V to 18-V supply, drawing a

maximum of 1800 μA of supply current. Package

options include the very small VSSOP-8 and the

SOIC-8. All versions are specified over the extended

operating temperature range of –40°C to +125°C.
