STMicroelectronics L6924U USB Compatible Battery Charger Datasheet
The L6924U is a fully monolithic battery charger designed to safely charge single-cell Li-Ion/Li-Polymer batteries from either a USB power source or an AC adapter. It features a fully integrated solution including a power MOSFET, reverse blocking diode, sense resistor, and thermal protection within a compact VFQFPN16 package.
The device supports programmable charge currents up to 1 A in AC adapter mode and 500 mA in USB mode. It operates in linear or quasi-pulse modes to manage power dissipation and includes closed-loop thermal control. Key features include programmable end-of-charge current, a charge timer, and interfaces for battery temperature monitoring via NTC or PTC thermistors.
