USB-C overvoltage protection for VBUS and CC lines
Product labels
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
• 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-Nucleo-
USBPDM1 and Nucleo-STM32G071RB

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