SCT63140FMAR

The SCT63140 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 15W 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 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 and 3.3V low dropout regulator LDO can provide power supplies to transmitter controller and external circuitries. The SCT63140 features input Under-Voltage Lockout UVLO, over current, short circuit protection, and over temperature protection. The SCT63140 is available in a compact 3mm*3mm QFN package.
