CYPD3172-24LQXQ

Application Specific Microcontrollers Overview

The CYPD3172-24LQXQ is a USB Type-C port controller from the EZ-PD™ CCG3PA-NFET family, designed for power adapters. It integrates a Cortex-M0 MCU subsystem with 64 KB flash and 4 KB SRAM, alongside a complete USB-PD transceiver and termination resistors. The device features an integrated high-voltage regulator (VDDD) powered by VBUS_IN (3.3 V to 21.5 V), a low-side current sense amplifier (LSCSA), two VBUS discharge FETs, and an NFET gate driver for load switch control. It supports USB PD 2.0/3.0 with PPS, QC4+, QC3.0, BC v1.2, Samsung AFC, and Apple charging protocols in a 24-pin QFN package.

Application Specific Microcontrollers Procurement Notes

Verify component authenticity through authorized Infineon distributors or certified partners. Confirm the specific ordering suffix matches the required firmware version (programmable vs. preprogrammed). Check for End-of-Life (EOL) status notifications prior to finalizing procurement plans to ensure supply continuity.

Application Specific Microcontrollers Selection Notes

Select this component for designs requiring integrated secondary-side feedback control via opto-coupler or direct feedback. Ensure the application operates within the 3.3 V to 21.5 V input range. Verify that the 24-QFN package fits the PCB layout constraints and that the external thermistor connection on GPIO3 aligns with thermal management requirements.
