TCPP: USB Type-C port protection for STM32 microcontrollers
for source, sink, and dual role power applications
USB Type-C overvoltage and overcurrent protection for STM32 MCUs
USB Type-C peripherals need VBUS surge protection against defective chargers and cables, while source and dual role functions for power delivery require overcurrent defense, and the limited pin spacing in USB Type-C connectors can lead to VBUS shorts that require CC line surge protection.
TCPP Application-Specific Integrated Products (ASIP), companion chips for STM32 microcontrollers offer a cost-effective solution for incorporating these key protections.
