HOW DOES IT WORK?
USB-C Sink 2 Click is based on the AP33772, a high-performance USB PD sink controller from Diodes Incorporated. The host MCU can control the PPS with 20mV/step voltage and 50mA/step current. The PD controller supports overtemperature protection (OTP), OVP with auto-restart, OCP with auto-restart, one-time programming (OTP), power-saving mode, and a system monitor and control status register. For OTP, this Click board™ comes with an NTC temperature sensor, with selectable temperature points (25°C, 50°C, 75°C, 100°C) as a temperature threshold. The onboard FAULT LED serves as a visual presentation of the negotiation mismatch. The Multi-time programming (MTP) is reserved for future configuration.

This USB Type-C power delivery sink controller requires power from a standard USB source adapter, in our case from the USB connector labeled USB-C PD-IN, and then delivers power to connected devices on the VSINK connector. Between USB and VSINK terminal stands a pair of MOSFETs, according to the AP33772's driver for N-MOS VBUS power switch support. The PD controller can control the external NMOS switch ON or OFF (all control is done via the I2C interface). The USB C connector acts as a PD-IN discharge path terminal with a USB Type-C configuration channels 1 and 2. The presence of the power supply on the USB C is indicated over the VBUS LED.
The AP33772 is equipped with several GPIOs. The user-configurable GPIO1 and GPIO2 are available on the side header labeled GP1, and GP2, with additional GND. Also, this Click board™ has several test pads for testing purposes. The 5V and 3.3V LDO voltage output can be measured over the V5V and V3V pads, and voltage feedback over the VFB pad.
USB-C Sink 2 Click uses a standard 2-Wire I2C interface to communicate with the host MCU. The interrupts from AP33772 can be monitored over the INT pin. One of the additional features of the USB-C Sink 2 Click is the ability to track the VBUS voltage over the AN pin of the mikroBUS™ socket.
This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. Also, this Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.
