DESCRIPTION

The MPQ8112 and MPQ8112A are low-cost,

unipolar, high-side current-sense amplifiers.

The devices operate from a 2.7V to 60V supply

and typically consume a 300μA current. They

are ideal for today’s automotive systems,

industrial supplies, and systems where

battery/DC current monitoring is critical.

High-side current monitoring is especially useful

in battery-powered systems, since it does not

interfere with the ground path of the battery

charger. The common mode input ranges

between 0V and 60V with a 700kHz high

bandwidth. That makes these devices suitable

for use in inside control and short-circuit

protection loops.

The MPQ8112 directly converts a differential

input voltage to a voltage output with built-in

internal common input resistors and a load

resistor. The MPQ8112 has a 50V/V gain.

The MPQ8112A converts the differential input

voltage to a current output. This current is

converted back to a voltage with an external

load resistor. The MPQ8112A has an

adjustable gain based on the external common

input resistors and load resistor.

Both the MPQ8112 and MPQ8112A are

available in TSOT23-6L packages.
