Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The SC2021AQDER SC2021A is a Type-C/PD and DPDM fast charging controller. It complies with the latest Type-C and PD 3.0 standards, supports proprietary high voltage fast charging protocols and has dual DPDM interfaces. Its main applications are wall charger adapters, travel charger adapters and car chargers. The SC2021A has been designed to minimise external components by incorporating a 32k internal power supply, an I2C interface and protection circuitry. The SC2021A provides a cost effective solution for many applications with its 32-bit high performance microcontroller core with 32k-Byte MTP ROM and 2.5k-Byte RAM integrated internally, The SC2021A is available in a QFN 4mm x 4mm 32-pin package.
