STMicroelectronics TCPP01-M12

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 USB Type-C™ power delivery standard 3.1, standard power range (SPR), up to 100 W
• Open-drain fault reporting
• ECOPACK2 compliant
• USB-IF certification as power-sinking device with test ID: 5205 on X-NUCLEO-SNK1M1 and Nucleo-STM32G071RB

Applications

• Any USB Type-C device used in UFP/sink configuration: using 5 V only or any PDO from USB power delivery, incl. PPS
• Power sinking devices: POS, gaming, healthcare, USB hub, IoT gateways
• Smart speakers, earphones, smart glasses, power tools, etc.
