MAX8922LETB+ [Analog Devices]

The MAX8922L is a linear battery charger designed for single-cell Li+ batteries. It operates from a DC source between 4.45V and 7V, with input withstand up to 30V. It features programmable fast-charge and top-off currents via a single-pin interface (EN/SET), includes thermal regulation for optimized charge rate, and provides status outputs (CHG and POK). The device requires no external FET, blocking diode, or sense resistor, and comes in a tiny 10-pin TDFN package.
