Datasheet TCPP01-M12 (STMicroelectronics)

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

Description Packing
Tape and reel The TCPP01-M12 (type-C port protection) is a single chip solution for USB type-C PPS compliant port protection that facilitates the migration from USB legacy connectors type-A or
Description
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-
Companion chip
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
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
USB Type-C with
example battery” management logic that is compliant with the latest USB power delivery
power delivery
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.
