Detailed Description

USB-C Sink 2 Click Example.

Description

This example demonstrates the use of the USB-C Sink 2 Click board™ by setting DC power requests and control for Type-C connector-equipped devices (TCD).

The demo application is composed of two sections :

Application Init

Initializes I2C and ADC modules and log UART. After driver initialization the app set default settings.

Application Task

In this example, the app configures Power Data Objects (PDO) highest priority profile and requests power from a standard USB PD source adapter. After connecting the PD source and USB-C Sink 2 Click with the Type-C cable, the app gets the total number of valid PDO's and switches all PDO configurations every 10 seconds. When the PD source accepts the request, the app displays information about VOUT Voltage [mV] and Current [mA] and the temperature [degree Celsius] of the USB-C connector.

Note

FAULT LED flickering notified of the system status:

Charging: Breathing light (2 sec dimming), 1 cycle is 4 sec.
Fully charged: Continuously lit Charging current < 500mA.
Mismatch: 1s flicker Voltage or power mismatch. Non-PD power source, 1 cycle is 2sec.
Fault: 300ms flicker OVP, 1 cycle is 600ms.
