The SC9603 is a highly integrated wireless power transmitter SOC solution that contains both digital microcontroller and analog front end (AFE). The microcontroller includes a high performance 32-bit digital core, rich memory and peripherals. The AFE includes a full-bridge power MOSFETs, current sense amplifier, communication demodulator, linear regulator and protection circuit. The SC9603 supports various type of transmitter include both Extended Power Profile (EPP) and Baseline Power Profile (BPP) defined in WPC V1.2.4. The SC9603 integrates DP/DM interface. To implement an EPP transmitter system, the SC9603 can request a high voltage from the adapter through DP/DM interface. The SC9603 supports foreign object detection (FOD) by continuously monitoring the input voltage and input DC current. Besides, the SC9603 also supports input under-voltage lockout (UVLO), over-current protection (OCP) and over-temperature protection (OTP). These protections further enhance the reliability of the total wireless power transmitter system. The SC9603 is available in a compact 3 x 3 mm FCQFN package.
