Overview

The AP33772 is a highly integrated USB Power Delivery (PD) 3.1 Sink controller designed to manage power negotiation and protection for USB Type-C devices. Supporting a wide input voltage range from 3.3V to 31V, it allows an external MCU to monitor and control the power profile via an I2C interface.

Why Choose This Part

It offers comprehensive protection including 34V short-circuit protection on CC pins and integrated moisture detection for the Type-C connector. The device simplifies system design by including an N-MOS output enable driver and internal junction temperature monitoring.

Applications

USB-C Powered Tools
Ideal for migrating power tools and portable equipment from barrel jacks to USB-C charging.
Battery Charging Sinks
Manages high-power charging profiles for multi-cell lithium-ion battery packs.
Industrial IoT Nodes
Provides reliable power delivery and moisture detection for ruggedized sensors and controllers.
Smart Home Appliances
Negotiates specific voltage rails for small appliances using standard USB-C power adapters.
