AP33772S I2C USB PD3.1 EPR SINK CONTROLLER
Description
The AP33772S 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 flexible Type-C Connectorequipped Devices (TCDs) with an embedded host MCU (Micro Controller Unit) and I2C interface pins (SCL, SDA).
Through the I2C interface interaction and interrupt mechanism, the host MCU sets up proper desired power profile (programmable voltage and current) with relevant threshold (OTP, OCP, etc.) and delegates PD negotiation tasks to the AP33772S.
