The TCPP01-M12 features 22 V tolerant ESD board STM32G071RB or protection as per IEC61000-4-2 level 4 on USB Type-C connector configuration Nucleo-STM32G474RE channel (CC) pins. For a safe and reliable USB Type-C implementation, the TCPP01- M12 provides overvoltage protection on CC1 and CC2 pins when these pins are ST NUCLEO-L552ZE-Q, development subjected to short circuit with the VBUS pin that may happen when removing the STM32L562E-DK, board with USB Type-C cable from its receptacle. For sink applications, TCPP01-M12 triggers STM32L552E-EV TCPP01-M12 an external N-MOSFET on VBUS line when a defective power source applies a voltage higher than selected OVP threshold. Also, the TCPP01-M12 integrates a ST reference USB-C power adaptor dead battery management logic that is compliant with the latest USB power delivery design STEVAL-USBPD27S specification. The power supply of the TCPP01-M12 for sink applications operated with a battery can be provided by an MCU 3.3 V GPIO in order to drop the power consumption in cable not attached condition down to 0 nA. This low power mode will extend the battery operating life when no source equipment is attached. The TCPP01-M12 can also be used to protect source (provider) applications, and it can support programmable power supply feature from the USB-C power delivery specification.
