Overview

The CYPD3171-24LQXQ is a highly integrated USB Type-C port controller belonging to the EZ-PD CCG3PA family. It combines an Arm Cortex-M0 processor with specific hardware blocks for Power Delivery 3.0, including PPS support and integrated VBUS regulation for power adapter designs.

Why Choose This Part

This SoC reduces BOM count by integrating VBUS-to-CC short protection, high-voltage LDOs, and gate drivers for VBUS FETs. The inclusion of a 64KB flash-based Cortex-M0 allows for field-upgradable firmware to maintain compliance with evolving USB-IF standards.

Applications

USB-C Power Adapters
Primary controller for AC-DC power bricks supporting PD 3.0 and Programmable Power Supply (PPS) modes.
Mobile Chargers
Implementation of fast-charging protocols including QC 4.0, Apple 2.4A, and Samsung AFC in a compact 4x4mm form factor.
Power Banks
Managing bidirectional power flow and battery charging via USB-C and USB-A ports using integrated current sense amplifiers.
Car Chargers
DC-DC power conversion management for automotive aftermarket chargers with integrated OVP and OCP protection.
