Features• USB PD port (sink)• STUSB4500 USB Power Delivery controller, certified for:

– USB type-C™ (rev1.2)– USB PD (rev2.0)– TID: 1000133

• Compliant with USB PD (rev3.0)• 5 V on-board DC-DC• VBUS power switches and discharge path• Support to up to 3 power data objects (PDO)• Short-to-VBUS protections on CC pins (22 V) and VBUS pins (28 V)• Customizable start-up profiles• Multiple output paths• Compatible with NUCLEO-F072RB development board for configuration and

debug interface• CE certified• RoHS and China RoHS compliant

DescriptionThe STEVAL-ISC005V1 evaluation board is a ready-to-use USB PD sink based onSTUSB4500. It handles the USB PD negotiation with a source to enable one or morecharging paths.

An L7985 device ensures step-down conversion from the negotiated VBUS sink inputto output a 5 V regulated supply which optionally allows powering an MCU evaluationboard or any other system.

Several LEDs report power availability on each of the 4 available outputs.

The USB PD sink port is pre-configured with three different PDOs to address a broadrange of applications (5 V, 15 V and 20 V).

PDOs can be easily customized thanks to a graphical user interface (GUI).
