L6924U

Battery Chargers Overview

The L6924U is a monolithic battery charger IC for single-cell Li-Ion/Polymer packs. It integrates a power MOSFET, reverse blocking diode, and sense resistor in a 16-VFQFPN (3x3 mm) package. Operating input voltage ranges from 2.5 V to 12 V with a maximum charge current of 1 A. The device supports linear mode for regulated adapters and quasi-pulse mode for current-limited sources. It features closed-loop thermal control, programmable pre-charge/fast-charge currents, end-of-charge thresholds, and timers. Two open-collector diagnostic outputs allow LED driving or microcontroller communication.

Battery Chargers Feature Summary

• Fully integrated solution combining power MOSFET, reverse blocking diode, and sense resistor
