Overview

The CYPD3174-24LQXQ is a highly integrated USB Type-C Port Controller belonging to the EZ-PD CCG3PA family. It features an integrated Arm Cortex-M0 processor and 64kB of flash memory, specifically designed to handle USB Power Delivery (PD 3.1) and various legacy charging protocols in a compact 24-pin QFN package.

Why Choose This Part

This controller minimizes external component count by integrating VBUS regulation, low-side current sensing, and system-level ESD protection. Its wide operating voltage up to 24.5V and support for multiple fast-charging protocols (Apple 2.4A, AFC, BC 1.2) make it a versatile single-chip solution for modern power delivery designs.

Applications

USB-C Power Adapters
Ideal for wall chargers and power bricks requiring support for Programmable Power Supply (PPS) and fast-charging standards like QC 4.0.
Mobile Power Banks
Manages battery charging and discharging over USB-C while providing integrated voltage regulation and protection features.
Car Chargers
Utilizes the wide 3V to 24.5V supply range and integrated current sense amplifier for automotive accessory charging solutions.
PC Peripheral Charging
Provides Power Delivery negotiation for docks and monitors that need to supply power to connected laptops.
