Compact chip provides comprehensive protection for USB Type-C ports

STMicroelectronics

The STMicroelectronics TCPP01-M12 is a protection device for USB Type-C® ports.

The TCPP01-M12 enables system designers to quickly and safely replace older USB Type-A or Type-B ports with the latest USB technology. By implementing protection with the TCPP01-M12, OEMs can maintain the safety and reliability of products featuring the latest high-speed and high-power connector interface.

 

Features provided by the TCPP01-M12 include protection against a defective power adaptor, to prevent damage to the device if a faulty power supply applies the wrong power profile. The product also provides short-circuit protection between the power bus pins and configuration channel (CC) lines.

 

The TCPP01-M12 is suited to the protection of 5 V-only connections managed by general-purpose microcontrollers such as STM32 devices. It can also work with the 20 V/100 W USB Type-C Power Delivery controller integrated in the STM32G0, STM32G4, STM32L5 and STM32U5 MCUs.

 

The TCPP01-M12 can be used to protect device (consumer) applications, and can support the programmable power-supply feature of the USB Power Delivery 3.0 standard.

 

Supplied in a 12-lead QFN package, the TCPP01-M12 measures 3.0 mm x 3.0 mm x 0.9 mm.

Features

  • Over-voltage protection adjustable up to 22V
  • ±8 kV ESD protection for contact discharge
  • Integrated gate driver
  • Zero current when no USB cable attached
  • Junction-temperature range: -40°C to 125°C

Applications

  • Any battery-powered device with a USB-C charging port
  • Mobile point-of-sale terminals
  • Power tools
  • Medical devices
  • USB hubs
  • Smart speakers
