MPQ8112/MPQ8112A

60V, High-Side Current-Sense Amplifier,

AEC-Q100 Qualified

DESCRIPTION

FEATURES

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.

(MPQ8112A)

±1% Current-Sense Gain Accuracy

High-Current Sensing Capabilities

Available in a 6-Lead TSOT23 Package

Available in AEC-Q100 Grade 1

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.



APPLICATIONS

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.



Advanced Driver Assistance Systems

(ADAS)



Sensor Fusion Systems

Electric Power Steering (EPS) Systems

Electronic Stability Control (ESC) Systems

Brake Systems

Battery-Operated Systems

Energy Management Systems

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.
