The TCPP01-M12 (Type-C port protection) is a single chip solution for USB Type-C™ port protection that facilitates the migration from USB legacy connectors type-A or type-B to USB Type-C™ connectors. The TCPP01-M12 features 22 V tolerant ESD protection as per IEC61000-4-2 level 4 on USB Type-C™ connector configuration 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 subjected to short circuit with the VBUS pin that may happen when removing the USB Type-C™ cable from its receptacle. For sink applications, TCPP01-M12 triggers an external N-MOSFET on the VBUS line when a defective power source applies a voltage higher than selected OVP threshold. Also, the TCPP01-M12 integrates a “dead battery” management logic that is compliant with the latest USB power delivery specification. The MCU 3.3 V GPIO provides the power supply of the TCPP01-M12 for sink applications operated with a battery in order to drop the power consumption in “cable not attached” condition down to 0 nA. This low-power mode extends 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 a programmable power supply feature from the USB Type-C™ power delivery specification.
