Overview

The CYPD3177-24LQXQ, also known as EZ-PD BCR (Barrel Connector Replacement), is a highly integrated USB Type-C port controller designed to replace legacy barrel connectors and custom power plugs. It implements a complete USB Power Delivery (PD) sink profile, enabling devices to negotiate power from USB-C chargers without requiring custom firmware development.

Why Choose This Part

This controller offers a turnkey solution with an integrated USB PD policy manager and load switch controller with soft start, significantly reducing PCB footprint. It supports a wide input voltage range from 3V to 24.5V and includes essential system-level ESD protection and overvoltage protection on-chip.

Applications

Barrel Connector Replacement
Retrofitting legacy electronic devices to accept power from universal USB-C PD power adapters instead of proprietary DC jacks.
Battery Powered Tools
Integrating high-speed charging into cordless tools and portable equipment using standard USB-C infrastructure.
Consumer Electronics
Implementing power-only USB-C sink functionality in speakers, cameras, and small appliances up to 100W.
