The MAX4172ESA+ is a precision, high-side current-sense amplifier designed for battery and DC power-line monitoring in portable systems. It features a wide input common-mode range of 0V to 32V, independent of the supply voltage, ensuring reliable current sensing even with deeply discharged batteries.
This amplifier operates with a supply voltage range of 3V to 32V and offers a typical full-scale accuracy of ±0.5% over temperature. It provides a bandwidth of 800kHz, making it suitable for various applications including closed-loop battery chargers and general-purpose current sources. The device has a current output that can be converted to a ground-referred voltage using a single resistor.
Available in space-saving SOIC and µMAX packages, the MAX4172ESA+ is ideal for applications where board space is critical. Its high-side monitoring capability does not interfere with battery charger ground paths, making it particularly useful in battery-powered equipment.
Key electrical characteristics include a typical input bias current of 42.5µA and an input offset voltage of 100µV. The device also features an open-collector power-good output (PG) that indicates when the supply voltage is adequate for proper operation.
