Type-C Connector Current Mode Detection (OUT1, OUT2)

PI5USB30216C can detect different host current modes and other accessories per CC1/CC2 setting. When PI5USB30216C

operates in device mode (or dual role mode acting as device), it detects CC1/CC2 status to determine host charging current modes

and reports to the system using OUT1 and OUT2 pins. OUT1 and OUT2 will always stay hi-z unless medium or high current

mode is detected.

Type-C Connector Current Mode Setting in Host Mode

When PI5USB30216C is configured as a host, it can only be set to Default Current Mode (current source Ip=80uA). I2C control is

required to set current mode to 1.5A or 3A.

Audio Adapter Accessory Detection (OUT3)

PI5USB30216C detects audio adapter accessory attachment as per CC1/CC2 setting. This is reported by the OUT3 pin. OUT3

will be pulled low when an audio adapter accessory attachment is detected. Otherwise, OUT3 is hi-z.

ADDR, ID, ENB, and Dead Battery Startup

Functionality of the ADDR, ID, and ENB pins are the same for pin control or I2C control modes. Dead battery startup operation

is also the same for pin control and I2C control modes. Please refer to previous section for detail description.
