IntroductionThe STEVAL-ISC005V1 evaluation board is a ready-to-use USB PD sink based on STUSB4500. It handles the USB PDnegotiation with a source to enable one or more charging paths.

An L7985 device ensures step-down conversion from the negotiated VBUS sink input to output a 5 V regulated supply whichoptionally allows powering an MCU evaluation board 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 broad range of applications (5 V, 15 V and 20 V).

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

1 Getting started

1.1 Board overviewThe STEVAL-ISC005V1 USB Type-C™ port is pre-configured with 3 PDOs at fixed voltage:• PDO1 : +5 V/1.5 A - low priority• PDO2 : +15 V/1.5 A - medium priority• PDO3 : +20 V/1.0 A - high priority

The STEVAL-ISC005V1 evaluation board 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

The STUSB4500 operates in dead battery mode: when connected to a SRC or DRP device, it presents Rd on CClines, requests 5 V and negotiates PDO voltage, according to the source capabilities.Whatever is the negotiated voltage, an on-board DC-DC provides +5 V to supply external devices.The LEDs on the board indicate the status :• attachment and orientation• negotiated PDO• GPIO status

The STUSB4500 can also be supplied by the micro-B connector.

1.2 Board usage

1.2.1 Power pathsWhen the STUSB4500 SNK is attached to the SRC device, and voltage on VBUS is in the proper range,VBus_EN_SNK signal is asserted low to enable connection between VBUS and Vsnk signal.When PDO2 voltage is negotiated, Power_OK2 signal is asserted low to provide power on Vsnk_PDO2 signal.When PDO3 voltage is negotiated, Power_OK3 signal is asserted low to provide power on Vsnk_PDO3 signal.
