| Description & Applications | 500mA USB Port or AC Adapter Lithium-Ion/Polymer Battery Charger Designed to operate from a DC power source or USB port up to an input voltage of 6.5V. It requires just one external component. When charged from an AC adapter or USB port, the battery charging current can be set by an external resistor up to 500mA. In the event of an over-voltage, short-circuit, or over-temperature failure, the device will automatically shut down, thus protecting the charging device, control system, and the battery under charge. A status monitor output pin is provided to indicate the battery charge status by directly driving an external LED. Applications： Bluetooth Headsets DECT Headsets Digital Still Cameras MP3, Portable Music, and Portable Media Players Personal Data Assistants (PDAs) Wrist Watches Other Lithium-Ion/Polymer Battery-Powered Devices |
