Product details

Overview

CYPD3175-24LQXQ from Infineon is a single-chip USB Type-C port controller with integrated Arm® Cortex®-M0 MCU (64-KB Flash, 8-KB SRAM), full USB PD 3.1 + PPS support, dual legacy charger detection (QC 4.0, Apple 2.4A, AFC, BC 1.2), and analog VBUS regulation with low-side current sense amplifier - deployed in PC adapters, car chargers, and power banks.

For engineers reviewing the CYPD3175-24LQXQ datasheet, CYPD3175-24LQXQ pinout, CYPD3175-24LQXQ application, or CYPD3175-24LQXQ equivalent, this device delivers verified CC-line BMC PHY, integrated RP/RD termination switching, ±8-kV contact ESD on CC/VBUS pins, and hardware OVP/OCP/SCP protection - critical for robust consumer-grade USB-C power delivery design.

Technical Context

The CYPD3175-24LQXQ implements a dedicated USB PD 3.1 subsystem with half-duplex BMC physical layer, collision-avoidance logic, and programmable RP/RD resistor switching per role (DFP/UFP/dead-battery). Its analog VBUS regulation uses direct feedback or optocoupler interface with shunt regulator function and supports constant-voltage or constant-current modes.

Two 8-bit SAR ADCs sample GPIO, DP/DM, and VBUS_C_MON_DISCHARGE signals using internal bandgap or VDDD reference; dual SCB blocks provide configurable I²C/SPI/UART; and two PFET gate drivers control high-side VBUS path switches with integrated discharge FETs and OTP monitoring via ADC.

Equivalent & Alternatives

The following parts are listed as comparable options for similar USB Type-C port controller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
CYPD3174-16SXQ	16-pin SOIC package; lacks second DP/DM pair and one ADC channel; same MCU and PD stack	Targeted for cost-sensitive single-port adapters without legacy Type-A support	Select when board space permits SOIC and only one charging port is required
STUSB4500QTR	Standalone PD controller (no MCU); requires external microcontroller for PPS and proprietary charging logic	Suitable for designs where host MCU handles policy engine and firmware updates	Choose when existing MCU infrastructure exists and USB-C control is offloaded to dedicated PHY

Compared with CYPD3174-16SXQ, the CYPD3175-24LQXQ adds dual DP/DM support and enhanced ADC resources for multi-protocol charging; versus STUSB4500QTR, it integrates full policy engine and firmware upgradability - reducing system-level BOM and validation effort.

FAQ

Does CYPD3175-24LQXQ support USB PD 3.1 Programmable Power Supply (PPS)?

Yes, CYPD3175-24LQXQ natively supports USB PD 3.1 PPS mode with 20-mV/50-mA resolution and sub-100-ms voltage transition time. The integrated Cortex-M0 executes the PPS policy engine in firmware, enabling dynamic voltage adjustment during charging without host intervention.

What is the maximum VBUS voltage the device can withstand on CC pins during accidental shorts?

The CC1 and CC2 pins tolerate up to 22 V DC for 1000 hours and 17 V indefinitely under VBUS short conditions, per Infineon's characterization data. This protection is implemented in silicon and requires no external components - validated per IEC61000-4-2 ESD testing.

Can CYPD3175-24LQXQ operate without an external crystal or oscillator?

Yes, it includes an integrated precision oscillator (±2% accuracy) that eliminates the need for external clock components. The internal oscillator drives the MCU, USB PD PHY, and timers - reducing BOM count and PCB area while maintaining USB timing compliance.

How is firmware updated in-system for CYPD3175-24LQXQ?

Firmware updates occur via two methods: (1) SWD interface during manufacturing or debug, and (2) over-the-CC line using vendor-defined PD messages - enabling field upgrades without physical access. Both paths use AES-128 encrypted images and signature verification to prevent unauthorized code execution.
