The SCT63252 is a highly integrated Power Management IC allows achieving high performance, high efficiency and cost effectiveness of wireless power transmitter system compliant with WPC specification to support up to 25W power transfer, working with a wireless application specific controller or a general MCU based transmitter controller.

This device integrates a 4-MOSFETs full bridge power stage，gate drivers, a 5V LDO, a 3.3V LDO, communication demodulator, Q-factor detection and input current sensor for both system efficiency and easy-to-use.

The proprietary gate driving scheme and integrated PVIN cap optimizes the performance of EMI reduction to save the system cost and design. The proprietary lossless current sensing circuitry with ±2% accuracy monitors input current of full bridge to support Foreign Object Detection FOD and current demodulation. The build-in 5V and 3.3V low dropout regulator LDO can provide power supplies to transmitter controller and external circuitries. The low IQ mode with ultra-low quiescent current to decrease power loss for Q factor detection.

The SCT63252 features input Under-Voltage Lock-out UVLO, over current, short circuit protection, and over temperature protection.

The SCT63252 is available in a compact 4mm*4mm FC-QFN package.
