CYPD3174-16SXQ

Application Specific Microcontrollers Overview

The CYPD3174-16SXQ is a USB Type-C port controller from the EZ-PD™ CCG3PA family, manufactured by Infineon Technologies. It integrates 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). Key features include integrated VBUS regulation, low-side current sensing, and system-level ESD protection rated at ±8-kV contact discharge and ±15-kV air gap discharge. It operates within a voltage range of 3.0 V to 24.5 V on VBUS_IN_DISCHARGE and is housed in a 16-pin SOIC package.

Application Specific Microcontrollers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required package and temperature grade. Ensure compliance with RoHS directives as indicated in official documentation before procurement.

Application Specific Microcontrollers Selection Notes

Select this model for designs requiring a single USB Type-C port and one Type-A port. The 16-pin SOIC package is suitable for space-constrained applications compared to the 24-pin QFN variant. Ensure the application requires support for USB PD 3.1 and legacy charging protocols like QC 4.0.

Application Specific Microcontrollers Part Context

This component belongs to the EZ-PD™ CCG3PA series, designed for consumer USB Type-C applications. It utilizes Infineon's proprietary M0S8 technology to provide high integration, reducing bill of materials by combining MCU, transceiver, and protection circuits into a single chip.

Application Specific Microcontrollers Replacement Considerations

The CYPD3174-24LQXQ serves as a functional alternative within the same family but utilizes a 24-pin QFN package instead of the 16-pin SOIC. Pinout compatibility differs; verify footprint and schematic adjustments are feasible before substitution.
