Torex Semiconductor, Ltd. Battery Chargers XC6806A425DR-G

The XC6806A425DR-G is a linear charger IC designed for single-cell lithium-ion and lithium-polymer batteries. It features a system power supply function that prioritizes power to the system over battery charging. The charge current is adjustable via external resistance, with an internal limit of 450mA that adapts based on the load current. The device includes safety features such as temperature monitoring compliant with JEITA standards, charge timers, under-voltage lockout (UVLO), thermal control, and reverse current prevention. This IC operates within a voltage range of 4.5V to 5.5V and supports charge voltages from 3.50V to 4.45V with a maximum charge current of 385mA. It is packaged in compact USP-10B or LGA-10B01 formats, facilitating easy integration into designs with minimal external components. The XC6806A425DR-G is suitable for applications in wearable devices, Bluetooth headsets, hearing aids, healthcare devices, and IoT sensors. It is also compliant with EU RoHS regulations, making it an environmentally friendly choice.
