STMicroelectronics TCPP01-M12

USB Type-C port protection for sink application

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 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.

Key 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 compliant with IEC 61000-4-2
Integrated gate driver and charge pump for an external N-channel MOSFET

Additional 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 batteryoperated "consumer/sink" applications
Integrated “dead battery” (RD resistors)
Over temperature protection (OTP)
Operating junction temperature from -40°C to 85°C
Complies with the latest USB Type-C and USB power delivery standards
Compliant with programmable power supply (PPS) for fast battery charging
Open-drain fault reporting
ECOPACK2 compliant
USB-IF certification as power sinking device with TID: 3036 on X-NucleoUSBPDM1 and Nucleo-STM32G071RB

Applications

Power sinking devices: POS, gaming, healthcare, USB hub, IoT gateways
Smart speakers, earphones, smart glasses, power tools, etc.

Available tools

X-NUCLEO-SNK1M1:

USB Type-C Power Delivery Sink expansion board based on TCPP01-M12 for STM32 Nucleo

The X-NUCLEO-SNK1M1 expansion board allows evaluating the features of TCPP01-M12 and the USB Type-C overvoltage protection for VBUS and CC lines suitable for Sink applications. The expansion board is designed to be stacked on top of any STM32 Nucleo-64 development board exploiting the characteristics of the USB Type-C and Power Delivery (UCPD) peripheral embedded in their microcontrollers.
