IFXCYPD3177-24LQXQT

Overview

The CYPD3177-24LQXQT is a USB Type-C Power Delivery (PD) sink-only controller designed to simplify the transition from barrel connectors to USB-C charging. It integrates a complete PD PHY, an MCU, and high-voltage protection, supporting a wide supply voltage range from 3V to 24.5V. This controller is specifically optimized to act as a Universal Fetch Port (UFP) for devices requiring up to 100W of power.

Why Choose This Part

It eliminates the need for custom firmware development by providing a pre-programmed, hardware-configurable solution for PD sink negotiation. The integrated VBUS-to-CC short protection and overvoltage protection (OVP) reduce external component count and PCB footprint. Its wide operating temperature range of -40 degrees C to 105 degrees C makes it suitable for demanding industrial and consumer environments.

Applications

Getting Started

Engineers can evaluate this controller using the CY4533 EZ-PD BCR Evaluation Kit, which provides a ready-made platform for testing different power profiles. Hardware configuration is primarily handled through resistor strapping on the pins to set voltage and current requirements. Detailed design files and the EZ-PD Configuration Utility are available from Infineon to assist in fine-tuning the PD contract negotiation.
