DESCRIPTION

The EV8110DS-00A is an evaluation board for

the MP8110, a low-cost, precision, high-side

current-sense amplifier. The input voltage

ranges from 2.5V to 40V. The output voltages

are proportional to the load current with a 1V

output corresponding to 5A of load current.

The MP8110 operates from a single 2.5V to

40V 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

1.4V to 40V 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.
