Demo board controls USB Type-C Power Delivery operations up to 100 W

The X-NUCLEO-DRP1M1 expansion board from STMicroelectronics enables designers to evaluate the features of the TCPP03-M20 USB Type-C PD controller, including the ability to protect the bus- and supply-voltage lines in dual role power (DRP) applications.

The expansion board can be stacked on top of any STM32 Nucleo-64 board which has a USB PD peripheral embedded in its microcontroller.

The X-NUCLEO-DRP1M1 demonstrates dead battery and sink operations, an integrated ST715PU33R linear regulator supplies the associated STM32 Nucleo development board. It also performs USB Type-C source operations when a compatible external source is connected to the board. In addition, the board supports dual-role data functionality for sourcing devices.

The X-NUCLEO-DRP1M1 complies with the USB Type-C and USB PD 3.1 specifications for the standard power range, and is USB-IF certified as a 100 W DRP solution supporting a programmable power supply.

The companion X-CUBE-TCPP software package contains application examples for NUCLEO-G071RB and NUCLEO-G474RE development boards. These can be ported to other development boards that have USB Type-C PD-enabled MCUs.
