CYPD3175-24LQXQ

Application Specific Microcontrollers Overview

The CYPD3175-24LQXQ is a consumer USB Type-C port controller from Infineon's EZ-PD™ CCG3PA family. It integrates an ARM Cortex-M0 processor, 64 KB flash, and a complete USB PD transceiver with termination resistors. The device supports USB PD Revision 3.1 including PPS mode and legacy charging standards like QC 4.0 and Apple 2.4A. It features integrated VBUS regulation, low-side current sensing, and system-level fault protection including OVP, OCP, and VBUS-to-CC short protection. Operating voltage ranges from 3.0 V to 24.5 V on the power input pin, with a core supply of 2.7 V to 5.5 V. The component is housed in a 24-pin QFN package.

Application Specific Microcontrollers Feature Summary

• Supports USB PD 3.1 (including PPS) and legacy charging protocols (QC 4.0, Apple 2.4A, AFC, BC 1.2)
• Integrates 32-bit ARM Cortex-M0 CPU with 64 KB Flash and 8 KB SRAM
• Includes analog VBUS regulation circuitry for direct feedback control
• Provides system-level ESD protection (±8-kV contact, ±15-kV air gap) and VBUS short protection

Application Specific Microcontrollers Applications

• PC power adapters
• Mobile chargers
• Car chargers
• Power bank applications

Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm package type and temperature grade. Ensure compatibility with the EZ-PD™ CCGx Power SDK for firmware development. Confirm that the selected variant includes the necessary dead-battery RD resistor bonding if used in power sink roles.

Application Specific Microcontrollers Selection Notes

Select this component for single-port Type-C applications requiring integrated primary/secondary side control capabilities. The CYPD3175 variant is specifically configured for DFP (Downstream Facing Port) roles with Direct Feedback Bootloader. Consider the 24-pin QFN package constraints and thermal requirements for high-power adapter designs.

Application Specific Microcontrollers Part Context

This part belongs to the EZ-PD™ CCG3PA series, designed for highly integrated USB Type-C solutions. It utilizes Infineon's proprietary M0S8 technology to reduce BOM by combining controller functions with voltage regulation and protection circuits. It is distinct from automotive-grade variants like the CYPD3196 which carry AEC-Q100 certification.

Application Specific Microcontrollers Replacement Considerations

Direct replacements within the same family include CYPD3171 and CYPD3174, though firmware configuration and specific pin bonding options (such as dead-battery RD) may differ based on the application role (DFP vs UFP). Verify pinout compatibility and memory size before substitution.
