The MPQ8112 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 MPQ8112 directly converts a differential input voltage (VIN) to a voltage output with integrated internal common input resistors and a load resistor. The device has a 50V/V gain.
The MPQ8112 is available in a TSOT23-6L package.
