SC2154Q
Type-C and Dual DPDM Fast Charge Controller

Introduce

 

SC2154Q is a Type-C and DPDM fast charge controller for automotive fast charge applications. It complies with the latest Type-C standards and supports the proprietary high voltage fast charge protocols with dual DPDM interfaces. It targets for the application with the power delivery up to 27W. SC2154Q minimizes external components by integrating USB PD baseband PHY, Type-C detection, dual DPDM PHYs, VBUS discharging paths, VCONN supply, 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. SC2154Q 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 Current (VCONN OCP) and VCONN Short Protection (VCONN SCP), so to effectively ensure stable and reliable operation of system. The SC2154Q is available in 32-pin QFN package.
