DESCRIPTION
The MP8100 is a low-cost, precision, high-side current-sense amplifier. This device operates from a single 2.5V to 18V supply and typically consumes 17μA. It is ideal for today’s notebook computers, cell phones and other 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 input common-mode range of 1.5V to 18V is independent of the supply voltage and ensures that the current-sense feedback remains viable even when connected to a 2-cell battery pack in deep discharge.
