TCPP01-M12
Datasheet USB type-C port protection
Features
• Overvoltage protection on VBUS, adjustable 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 charge pump to control the gate of an external N-channel MOSFET (which features a lower RDSON than a P-channel MOSFET) • Null quiescent current when no USB charging cable is attached for battery- operated "consumer/sink" applications
Product labels
• 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) as defined in latest USB PD specification • Open-drain fault reporting • ECOPACK2 compliant
Applications
• USB type-C used in sink configuration (consumer)
Product status link
• USB type-C used in source configuration (provider) TCPP01-M12 • USB type-C for UFP (upstream facing port) or DFP (downstream facing port) configuration
Product summary
• USB type-C power delivery, PPS compliant

USB type-C port type-B to USB type-C connectors. The TCPP01-M12 features 22 V tolerant ESD protection 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-

STM32 or STM8 USB type-C cable from its receptacle. For sink applications, TCPP01-M12 triggers an STM32 with external N-MOSFET on VBUS line when a defective power source applies a voltage UCPD support, higher than selected OVP threshold. Also, the TCPP01-M12 integrates a “dead

STM32L5, specification. The power supply of the TCPP01-M12 for sink applications operated STM32G0, with a battery can be provided by an MCU 3.3 V GPIO in order to drop the power STM32G4 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.
