Overview

The CYPD3176-24LQXQ is a highly integrated USB Type-C and Power Delivery (PD) controller based on an Arm Cortex-M0 core. Part of the CCG3PA family, it is specifically designed for power adapter and power bank applications, supporting both Sink and Source roles with integrated protection features.

Why Choose This Part

This controller offers a wide input voltage range from 3V to 24.5V and includes integrated VBUS gate drivers with in-rush current control, significantly reducing external component count. It provides robust system-level protection with on-chip overvoltage, overcurrent, and over-temperature circuitry, alongside 8-kV contact ESD protection.

Applications

USB-C Power Adapters
Used as the primary PD controller for wall chargers, supporting Programmable Power Supply (PPS) and legacy charging protocols like QC 2.0 and AFC.
Mobile Power Banks
Manages bidirectional power flow for portable batteries, handling both charging the internal cells and delivering power to downstream devices via USB-C.
PC Peripheral Chargers
Integrates into docks or specialized accessories to provide high-voltage charging over Type-C while managing VBUS gate drivers.

Getting Started

Developers can utilize the Infineon EZ-PD Configuration Utility to customize firmware parameters and the CCG3PA SDK for deeper firmware development. Hardware evaluation is typically performed using the CY4532 CCG3PA Evaluation Kit, which provides a reference design for power adapter and power bank use cases.

Also Consider

CYPD3171-24LQXQ IFXInfineon Technologies - An alternative CCG3PA variant often used in similar power adapter designs with slightly different feature sets for specific charging standards.
STUSB4500 STMicroelectronics - A standalone USB PD sink controller suitable for applications that only require receiving power without a full ARM Cortex-M0 programmable core.
