CYPD5125-40LQXI

Controllers Overview

The CYPD5125-40LQXI is a single-port USB Type-C controller from the EZ-PD CCG5 family, designed for dual-role and downstream-facing port applications. It integrates an ARM Cortex-M0 processor running at 48 MHz with 128 KB flash and 12 KB SRAM. The device supports USB Power Delivery 3.0 and includes two integrated USB analog muxes, SBU muxes, and charger detection blocks. Operating voltage ranges from 2.75 V to 21.5 V, with an industrial temperature range of -40 °C to +85 °C. It features IEC-compliant ESD protection on CC, D±, and SBU pins.

Controllers Feature Summary

• Integrated USB Power Delivery 3.0 support with fast role swap capabilities
• Dual integrated USB analog muxes and SBU crossbar switches for signal routing
• Built-in high-voltage LDO regulator supporting up to 21.5 V operation
• Comprehensive protection including overvoltage, overcurrent, and dead battery termination

Controllers Applications

• PCs and notebook computers
• Docking stations
• Thunderbolt hosts and devices

Controllers Procurement Notes

Verify component authenticity through authorized Infineon distributors or certified partners. Confirm package integrity and moisture sensitivity level handling procedures prior to assembly. Ensure ordering suffix matches required packaging specifications. Cross-reference datasheet revision *M for accurate pinout and electrical characteristics.

Controllers Selection Notes

Select this part for single-port Type-C implementations requiring integrated PD 3.0 control. Compare against CYPD5225 for dual-port requirements. Verify GPIO availability and SCB configuration needs against specific system interface constraints. Consider thermal management within the specified operating temperature range.

Controllers Part Context

This component belongs to the EZ-PD CCG5 series, which utilizes Cypress M0WS8 technology. It serves as a complete port control solution for USB Type-C and Power Delivery standards. The device replaces legacy discrete controllers by integrating PHY, transceivers, and MCU functions into a single QFN package.

Controllers Replacement Considerations

Refer to the CCG5C datasheet for pin-to-pin compatible replacement parts. NRND status indicates it is not recommended for new designs; verify alternative selection if applicable.
