Introduce
SC2021PQ is a Type-C / PD and DPDM fast charge controller for automotive applications. It complies with the latest Type-C and PD 3.1 standard and supports the proprietary high voltage fast charge protocols with dual DPDM interfaces. It targets for the wall adapters, travel adapters and car chargers. SC2021PQ 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, which provides cost effective solutions to many applications. SC2021PQ 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 SC2021PQ is available in 32-pin QFN package.
