Description:

Precision / High-Side Current-Sense Amplifiers

Features

* o Complete High-Side Current Sensing o Precision Internal Sense Resistor (MAX471) o 2% Accuracy Over Temperature o Monitors Both Charge and Discharge o 3A Sense Capability with Internal Sense Resistor (MAX471) o Higher Current-Sense Capability with External Sense Resistor (MAX472) o 100µA Max Supply

Applications

* requiring higher current or increased flexibility, the MAX472 functions with external sense and gain-setting resistors. Both devices have a current output that can be converted to a ground-referred voltage with a single resistor, allowing a wide range of battery voltages and currents. An open-collec
