CYPD3171-24LQXQT

Application Specific Microcontrollers Overview

The CYPD3171-24LQXQT is a highly integrated USB Type-C port controller from the EZ-PD™ CCG3PA family, designed for PC power adapters, mobile chargers, car chargers, and power banks. It features a 32-bit Arm Cortex-M0 processor with 64-KB flash and 8-KB SRAM. The device supports USB PD Revision 3.1, including Programmable Power Supply (PPS) mode, and legacy charging standards such as QC 4.0, Apple 2.4A, AFC, and BC 1.2. It integrates a complete Type-C USB PD transceiver, termination resistors, VBUS regulation circuitry, and system-level ESD protection. Operating voltage ranges from 3.0 V to 24.5 V on VBUS_IN_DISCHARGE or 2.7 V to 5.5 V on VDDD.

Application Specific Microcontrollers Procurement Notes

Verify component authenticity through authorized Infineon distributors or certified agents. Confirm package type matches the 24-pin QFN specification. Ensure storage conditions comply with moisture sensitivity level requirements prior to soldering. Cross-reference ordering codes to confirm specific tape-and-reel packaging configurations.

Application Specific Microcontrollers Selection Notes

Select this model for single-port Type-C applications requiring integrated VBUS regulation and legacy charging support. The 24-pin QFN package is suitable for compact designs needing extensive GPIO flexibility. Consider the dead-battery Rd bonding option if used in power bank sink roles. Verify thermal performance within the extended industrial temperature range of -40°C to +105°C.

Application Specific Microcontrollers Part Context

This component belongs to the EZ-PD™ CCG3PA consumer USB Type-C port controller family. It utilizes Infineon’s proprietary M0S8 technology to combine MCU capabilities with high-voltage analog functions. The CYPD3171 variant specifically targets applications requiring one Type-C port and one Type-A port support, distinguishing it from other family members with different port configurations.
