Description
19-1548; Rev 4; 7/09 Low-Cost, UCSP/SOT23, Micropower, High-Side Current-Sense Amplifier with Voltage Output General .
The MAX4372 low-cost, precision, high-side currentsense amplifier is available in a tiny, space-saving SOT23-5-pin package.
Features
* a voltage output that eliminates the need for gain-setting resistors and 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 w
