STMicroelectronics Extends USB Fast Charging over USB-C^® to Embedded Applications with USB-IF-Certified Development Board

USB-IF-certified solution provides solid reference for end-product certification

Promotes reuse and reliable interoperability for existing USB-C^® fast chargers and cables with USB Power Delivery support

Enables cost-effective system partitioning leveraging on-chip integrated features unique to ST

Geneva, June 29, 2020 – STMicroelectronics (NYSE: STM), a global semiconductor leader serving customers across the spectrum of electronics applications, is facilitating modernization of battery-powered products to capture the advantages of the latest USB Power Delivery (USB PD) technology including faster charging and easy reuse of USB-C^® chargers and cables.

“Using our USB-IF-certified development board, customers can now quickly add all of the USB-C benefits and reuse a solid platform for certification of their own board, contributing to a safe and reliable USB Type-C and USB PD ecosystem,” said Ricardo de Sa Earp, Group Vice President, Microcontrollers Division General Manager, STMicroelectronics.

“The unmatched capabilities of USB PD over USB Type-C cables and connectors is driving rapid innovation in a variety of USB charging applications and markets,” said Jeff Ravencraft, USB-IF President and COO. “Inventive solutions, such as ST’s new evaluation board, are vital to support the continued growth of USB-IF-certified USB PD and USB Type-C devices that consumers can rely on.”

The certified device (USB-IF TID: 3036) combines ST’s Nucleo-G071RB and X-Nucleo-USBPDM1 development boards. The Nucleo-G071RB features an STM32G0 microcontroller, the industry’s first general-purpose microcontroller to integrate a USB Type-C Power Delivery controller on-chip, enabling greater system integration as well as the possibility to support new application use cases. The X-Nucleo-USBPDM1 board contains ST’s TCPP01-M12 companion chip for port protection.

Moreover, customers can leverage the powerful tools and software of the STM32 ecosystem to complete their projects quickly and easily. Applications already using a microcontroller with legacy 5V USB charging can be updated to USB Type-C with only a small number of external components.

The Nucleo-G071RB ($10.32) and X-Nucleo-USBPDM1 ($23.50) are available now from st.com or distributors.

Further technical information

The TCPP01-M12 companion high-voltage analog front end integrates a charge pump to control the gate of an external power switch, which lets designers choose from economical N-channel MOSFETs that have lower RDS(on) than P-channel alternatives. There is also a low-power mode that draws 0nA when no cable is attached, enabling longer battery runtime.

The protection features built into the TCPP01-M12 include adjustable 5V to 22V overvoltage protection on VBUS, short-to-VBUS protection on configuration channel pins, dead-battery management, and IEC 61000-4-2 ESD protection up to ±8kV on VBUS and CC lines. The TCPP01-M12’s QFN12 package occupies 80% less board space than a discrete implementation.
