SC2021A
Type-C/ PD and Dual DPDM Fast Charge Controller
Introduce
 

SC2021A is a Type-C / PD and DPDM fast charge controller. It complies with the latest Type-C and PD 3.0 standards and supports the proprietary high voltage fast charge protocols with dual DPDM interfaces. It targets for the wall adapters, travel adapters and car chargers. SC2021A minimizes external components by integrating USB PD baseband PHY, Type-C detection, dual DPDM PHYs, VBUS discharging paths, VCONN supply, programmable feedback compensation, voltage and current sense, 10-bit high performance ADC, dual 10-bit DACs, NMOS gate driver, I2C interface and protection circuits. It contains a 32-bit high performance microcontroller core with 32kByte MTP ROM and 2.5kByte RAM, which provides cost effective solutions to many applications. SC2021A supports various protection mechanisms including Over Voltage Protection (OVP), Under Voltage Protection (UVP), Over Current Protection (OCP), Short Circuit Protection (SCP), Over Temperature Protection (OTP), DPDM Over Voltage Protection (DPDM OVP), CC Over Voltage Protection (CCOVP), VCONN Over Voltage (VCONN OVP), VCONN Over Current (VCONN OCP) and VCONN Short Protection (VCONN SCP), so to effectively ensure stable and reliable operation of system. The SC2021A is available in 32-pin QFN package.
