Product overview

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 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.

  • All features

    • VBUS overvoltage protection, adjustable from 5 V up to 22 V, with external N-channel MOSFET
    • 6.0 V overvoltage protection (OVP) on CC lines against short-to-VBUS
    • System-level ESD protection for USB Type-C™ connector pins (CC1, CC2), compliant with IEC 61000-4-2 level 4 (±8 kV contact discharge, ±15 kV air discharge)
    • Integrated gate driver and charge pump for an external N-channel MOSFET (featuring lower RDSON than a P-channel MOSFET) for low BOM cost
    • Null quiescent current when no USB charging cable is attached for battery-operated "consumer/sink" applications
    • Over temperature protection (OTP)
    • Operating junction temperature from -40°C to 125°C
    • Compliant with USB Type-C™ power delivery standard 3.1, standard power range (SPR), up to 100 W
    • ECOPACK2 compliant
    • USB-IF certification as power-sinking device with test ID: 5205 on X-NUCLEO-SNK1M1 and Nucleo-STM32G071RB
