XC6810A42C0R-G

XC6810 series is a linear charger IC for Li-ion battery with an ultra-small package compatible with a wireless charging and contact power supply. The charging current corresponds to 1mA to 25mA, and it has a current path function that supplies power to the system at the same time as charging. To realize an ultra-compact system, the battery over-discharge protection function, output Terminal Short protection function, and battery voltage monitor function or battery low voltage notification function are equipped. And the IC is equipped with a shutdown function and a wake-up function using an external push button to reduce battery consumption when the product is stored or unused. Application includes hearing aid, wireless earphones/headset wearable devices, wireless charging equipment, IoT devices, and smartcards.
