SC5003Q
Highly integrated wireless power transmitter analog front-end
The SC5003Q is a highly integrated wireless power transmitter analog front end that contains all of the analog components required to implement a WPC compliant transmitter. The SC5003Q integrates a full bridge power driver with MOSFETs, current sense amplifier, bootstrap circuit, communication demodulator and protection circuit. The SC5003Q can work with transmitter controller together to create a high performance wireless power transmitter that complies with both the WPC V1.2.4 Extended Power Profile (EPP) and Baseline Power Profile (BPP). The system supports foreign object detection (FOD) by continuously monitoring the amount of power transferred and comparing that to the amount of received power, as reported by the receiver. In order to do this, the SC5003Q measures the input DC current very accurately using a current sense amplifier. Besides, the SC5003Q also supports input under-voltage lockout (UVLO), input over-voltage protection (OVLO), overcurrent protection (OCP) and over-temperature protection (OTP). The SC5003Q is available in a compact 4 x 4 mm FCQFN21L package.
