SC2003
USB-PD Controller with Multiple Fast Charge Protocols Integrated
Introduce
 

The SC2003 is a highly integrated PD controller. It complies with the latest USB Type-C and PD 3.0 standards and supports the most popular high voltage fast charge protocols with up to 4x DPDM interfaces. The IC targets for notebooks, power banks and other mobile equipment applications. The SC2003 supports wide operation voltage range with 30V maximum rating, and without the need of an external LDO. It minimizes external components by integrating USB PD baseband PHY, Type-C detection, voltage and current sense, 10-bit DAC for VBUS regulation, 10-bit ADC, shunt regulator, VBUS discharging path, the NMOS gate driver, I2C interface and protection circuits, so to allow easy system design and low BOM cost. Its embedded micro-controller and 32-KB MTP provide highly flexible and cost effective solution to many applications. The SC2003 supports various protection mechanisms, including over voltage protection, under voltage protection, over current protection, short circuit protection, over temperature 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 SC2003 is available in 32-pin QFN packages.
