Description

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 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 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.
