MPQ8112A-AEC1

60V, High-Side Current-Sense Amplifier with Adjustable Gain, AEC-Q100 Qualified

Datasheet

Description

The MPQ8112A is a low-cost, unipolar, high-side current-sense amplifier. The device operates from a 2.7V to 60V supply, and typically consumes a 300μA current. It is ideal for automotive systems, industrial supplies, and systems where battery monitoring and DC current monitoring are critical.

High-side current monitoring is ideal in battery-powered systems, as 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, making the device suitable for inside control loops and short-circuit protection (SCP) loops. The MPQ8112A converts a differential input voltage (V_IN) to a current output, which is converted back to a voltage via an external load resistor. The device has an adjustable gain that is determined by the external common input resistors and the load resistor.

The MPQ8112A is available in a TSOT23-6L package.
