EVAL-SCS001V1: Standalone USB PD Controller for Power Sinking Devices

Summary

The EVAL-SCS001V1 reference design let you create a USB Type-C connector quickly and easily in order to power any application up to 100 W (20 V, 5 A).

The Type-C port is managed by the STUSB4500 in fully autonomous mode. When a connection is detected, the load device (VSNK) is connected to VBUS power by the PMOS controlled by the STUSB4500 device.

When attached to a Type-C / Power Delivery source, the STUSB4500 negotiates voltage according to the following priority list:

20 V / 1.0 A (PDO3 : preferred)
15 V / 1.5 A (PDO2)
5 V / 1.5 A (PDO1 : default)

A status LED indicates the voltage present on the VSNK:

Light blue = PDO1 / 5 V
Pink = PDO2 / 15 V
Bright blue = PDO3 / 20 V
