MPQ811x High-Side Current-Sense Amplifiers

Monolithic Power Systems (MPS) MPQ811x High-Side Current-Sense Amplifiers are ideal for automotive systems, industrial supplies, and systems where battery/DC monitoring is critical. High-side current monitoring is beneficial in battery-powered systems since it does not interfere with the ground path of the battery charger. The low-cost, unipolar, high-side current-sense amplifiers operate from a 2.7V to 60V supply and typically consume a 300µA current. These devices have common-mode input ranges between 0V and 60V with a 700kHz high bandwidth. Additionally, this makes the MPQ811x ideal for inside control and short-circuit protection loops.
