STMicroelectronics L6924U
The L6924U is a fully monolithic battery charger that safely charges single-cell LiIon/Polymer battery from either a USB power source or an AC adapter. The ideal solution for space-limited portable products integrates the power MOSFET, reverse blocking diode, sense resistor and thermal protection into a compact VFQFPN16 package. When an external voltage regulated adapter or USB port is used, the L6924U works in linear mode, and charges the battery in a constant current constant voltage (CC/CV) profile.| Part No. | L6924U |
