AP33771C

Description

The AP33771C is a highly integrated USB Type-C ® PD3.1 sink controller to support Extended Power Range (EPR)/Adjustable Voltage Supply (AVS) up to 28V and Standard Power Range (SPR)/ Programmable Power Supply (PPS) up to 21V. The device is targeted for DC power request and control for Type-C Connector-equipped Devices (TCDs) through simple external resistor setting.

For a simple TCD without a system MCU, the AP33771C initiates desired power request based on resistance values connected on the VSEL pin (voltage) and ISEL pin (current), after Power On Reset (POR), see Table 2 for details.

The AP33771C offers short protection between CC1/CC2 pins to adjacent high-voltage pin up to 34V. Smart built-in firmware of the AP33771C offers comprehensive safety protection schemes, including overvoltage protection (OVP), undervoltage protection (UVP), overcurrent protection (OCP), overtemperature protection (OTP), and moisture detection of the Type-C connector. An LED indicator is used to show the PD power negotiation status. The automatic cable voltage drop compensation is implemented to cover practical usage situations. The AP33771C can also indicate the insertion orientation of the TypeC attachment.
