Table 13. Hardware Configuration For The Ucpd Feature - ST STM32U5 User Manual

• V fault detection: UCPD_FLT: This signal is provided by the ST USB Type-C
BUS
used as fault reporting to MCU after a bad V
protection is set to 6 V maximum. (R41 is set to 2K7 to select 6 V maximum).
For more detail about UCPD with the TCPP01-M12 USB Type-C
application note USB Type-C Power Delivery using STM32 MCUs and MPUs (AN5225) related to USB Type-C
power delivery using STM32xx series.
Table 13 describes the hardware configuration for the UCPD feature.
