ST has created a USB Implementers Forum (USB-IF) certified evaluation board for up to 100W PPS USB Power Sinking Devices (PSD) that helps developers accelerate new designs and supports certification of the end product.

The aim is to facilitate modernisation 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.

The latest USB PD chargers can have power ratings up to 100W and can optimize charging by dynamically adjusting current and voltage thanks to the USB Programmable Power Supply (PPS) feature of USB PD.

Many products such as smart speakers, power tools, wearables, robots, g; aming controllers, power banks, and drones — traditionally recharged at 5V through older USB micro-B or proprietary connectors — can now leverage this ecosystem to benefit from the advantages and interoperability of USB-C technology while charging faster.

ST’s evaluation board (USB-IF TID: 3036) combines ST’s Nucleo-G071RB and X-Nucleo-USBPDM1 development boards.

The Nucleo-G071RB features an STM32G0 MCU which integrates  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.
