MP8100

Precision High-Side

Current-Sense Amplifier

The Future of Analog IC Technology

INITIAL RELEASE – SPECIFICATIONS SUBJECT TO CHANGE

DESCRIPTION

FEATURES

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.

•

Low-Cost, Compact Current-Sense Solution

17µA Typical Supply Current

2.5V to 18V Operating Supply Voltage

1.5V to 18V Input Common Mode Range

1µA Typical Shutdown Current

250µV Input Offset Voltage

High Current Sensing Capability

Low 100mΩ Output Impedance (Optional)

Available in an 8-Pin SOIC Package

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.
