The L6924D from STMicroelectronics is a fully integrated battery charger system designed for Li-Ion/Li-Polymer applications. It features an integrated power MOSFET, reverse blocking diode, sense resistor, and thermal protection, making it suitable for handheld devices, digital cameras, standalone chargers, and USB-powered chargers. The device supports both linear and quasi-pulse operation and is USB BUS-compatible. Key specifications include programmable charge current up to 1 A, pre-charge current, end-of-charge current, and pre-charge voltage threshold. The output voltage can be set to 4.1 V or 4.2 V with ± 1% accuracy. It also includes an interface for NTC or PTC thermistors for battery temperature monitoring and protection, along with status outputs for LED indication or host processor interfacing. The compact VFQFPN 16-lead package measures 3 x 3 mm, making it suitable for space-constrained applications.
