DESCRIPTION

The

INA200,

INA201,

and

INA202

are high-side

current-shunt

monitors

with

voltage

output.

The

INA200−INA202 can sense drops across shunts at

common-mode

voltages

from

−16V

to

80V.

The

INA200−INA202 are available with three output voltage

scales: 20V/V, 50V/V, and 100V/V, with up to 500kHz

bandwidth.

The INA200, INA201, and INA202 also incorporate an

open-drain comparator and internal reference providing a

0.6V threshold. External dividers are used to set the

current trip point. The comparator includes a latching

capability, which can be made transparent by grounding

(or leaving open) the RESET pin.

The INA200, INA201, and INA202 operate from a single

+2.7V to +18V supply, drawing a maximum of 1800

µA of

supply current. Package options include the very small

MSOP-8 and the SO-8. All versions are specified over the

extended operating temperature range of −40

°C to

+125

°C.
