Infineon Technologies EZ-PD™ CCG7SC USB-C PD & DC-DC Controllers

Infineon Technologies EZ-PD™ CCG7SC Single-port USB-C™ Power Delivery and DC-DC Controllers are highly integrated for single and multiport charging applications. The EZ-PD CCG7SC complies with USB-C and PD specifications. The Infineon PD solution with DC-DC controller includes an on-chip 32-bit ARM® Cortex®-M0 MCU, which allows the implementation of custom functions such as source policy management, load-sharing, and system peripheral control using PWMs, I²C, and SPI.
