FEATURES:

 

DESCRIPTION:

The SCT63042 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 7.5W 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 4.85V LDO, communication demodulator 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 4.85V low dropout regulator LDO can provide power supplies to transmitter controller and external circuitries.
The SCT63042 features input Under-Voltage Lockout UVLO, over current, short circuit protection, and over temperature protection.
The SCT63042 is available in a compact 2mm*2mm QFN package.

APPLICATIONS:

• WPC Compliant Wireless Chargers of 5W or 7.5W Systems for Watches, Mobiles or otherWearable Devices
• General Wireless Power Transmitters for 
• Consumer, Industrial and Medical Equipment
• Proprietary Wireless Chargers and Transmitters
