描述 Description

TS51224 is a fully-integrated wireless power receiver and battery charger for low-power, wearable applications that require a low-cost and space-saving solution. The TS51224 can operate by itself as a single-chip wireless power receiver in proprietary applications. It can also operate in conjunction with a wireless power controller or an application microcontroller to support the Qi or A4WP wireless charging standards as well as proprietary standards up to 2W combined system/battery?power.
