Product Details

The MAX8814 intelligent, stand-alone constant-current, constant-voltage (CCCV), thermally regulated linear charger is designed for charging a single-cell lithium-ion (Li+) battery.

The MAX8814 controls the charging sequence from the prequalification state through constant-current fast-charge and the final constant voltage charge. The IC achieves high flexibility by providing an adjustable fast-charge current through an external resistor. It also features a booting assistant circuit that distinguishes input sources and battery connection, and provides an output signal (ABO) for system booting.

The device operates over the extended temperature range (-40°C to +85°C), and is available in an 8-pin thermally enhanced 2mm x 2mm TDFN package (0.8mm max height).
