Detailed Description

USB-C Sink 3 Click example.

Description

This example demonstrates the use of USB-C Sink 3 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 SPI, I2C and ADC modules and log UART. After driver initialization the app set default settings: Voltage Selection: 5 [V] and Power: 15.0 [W].

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. It interprets power input requirements (voltage/current and maximum power) from the TCD. The example uses two configurations:

Voltage 5 [V] and Power 15.0 [W]
Voltage 9 [V] and Power 18.0 [W] Results are being sent to the Usart Terminal where you can track their changes.

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.
