SC2012
USB-PD Controller (Sink) with Multiple Fast Charge Protocols PHY Integrated
Introduce
 

The SC2012 is a highly integrated USB PD controller, mainly used for power consumer application. It complies with the latest USB Type-C and PD 3.0 and supports the most popular high voltage fast charge protocols DPDM interface. SC2012 is suitable for different kind of mobile devices. The SC2012 has the voltage rating of 30V. It minimizes external components by integrating USB PD baseband PHY, Type-C detection, voltage and current sense, 10bit high performance ADC, PWM output for VBUS regulation, NMOS gate driver, VBUS discharging path, I2C interface and protection circuits. It is embedded 32-bit high performance micro-controller with 32K-Bytes OTP, which provides cost effective solutions to many applications. SC2012 supports various protection mechanisms, including over-voltage protection, over current protection, short circuit protection, over temperature protection, under-voltage protection, DP/DM pin over voltage protection, and CC pin over voltage protection, so to effectively ensure the stable and reliable operation of the system. The SC2012 is available in 20-pin QFN packages.
