The SCT63341 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 50W power transfer, working with a wireless application specific controller ASIC or a general MCU based transmitter controller.This device integrates a 4-MOSFETs full bridge，gate drivers, a 5V step-down DC/DC converter, 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 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 buildin 5V step-down DC/DC converter and 3.3V low dropout regulator LDO can provide power supplies to transmitter controller and external circuitries. The SCT63341 features input under-voltage lock-out UVLO protection, over current protection, short circuit protection, and over temperature protection for robust design. The SCT63341 is available in a compact FCTQFN4X4-22L package.
