Product details
Overview
CYPD3174-16SXQT 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 support including PPS mode, dual legacy charger detection (QC 4.0, Apple 2.4A, AFC, BC 1.2), and analog VBUS regulation with low-side current sensing - deployed in PC power adapters, car chargers, and portable power banks.
For engineers reviewing the CYPD3174-16SXQT datasheet, CYPD3174-16SXQT pinout, CYPD3174-16SXQT application, or CYPD3174-16SXQT equivalent, key selection criteria include its 16-pin SOIC package, ±8-kV CC-pin ESD rating, integrated dead-battery RD resistors for sink-role operation, and hardware OVP/OCP/SCP protection on VBUS-connected pins.
Technical Context
The CYPD3174-16SXQT implements a dedicated USB PD 3.1 BMC physical layer with collision-avoidance half-duplex communication over CC1/CC2, configurable RP/RD termination, and embedded dead-battery RD bonding for power bank sink applications. It integrates two 8-bit SAR ADCs with GPIO/DP/DM muxing and internal bandgap or VDDD reference.
Its VBUS regulation subsystem combines analog feedback control (direct or opto-coupled), shunt regulator function, constant-voltage/constant-current modes, and low-side current sense amplifier with Rs-based sensing. Protection includes hardware OVP (configurable threshold), OCP, UVP, SCP, and VBUS-to-CC short tolerance up to 22 V DC for 1000 hours.

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 |
|---|---|---|---|
| CYPD3175-24LQXQ | 24-pin QFN package; adds second Type-C port support and enhanced GPIO count; same MCU and PD stack. | Targeted for multi-port adapters requiring dual Type-C outputs or Type-C + Type-A + legacy USB hub integration. | Select when board space allows QFN and dual-port functionality is required; not pin-compatible with SOIC CYPD3174. |
| STUSB4500QTR | Standalone PD controller (no MCU); no flash/SRAM; supports PD 3.0 only; no PPS or legacy charging blocks. | Suitable for simple fixed-output chargers where firmware customization or QC/AFC support is unnecessary. | Choose only for cost-optimized, non-upgradable designs lacking firmware flexibility or multi-protocol requirements. |
Compared with CYPD3175-24LQXQ, CYPD3174-16SXQT offers smaller footprint and lower assembly cost but lacks dual-port capability; versus STUSB4500QTR, it provides full firmware programmability, PPS, and integrated legacy charging - critical for consumer-grade adaptive chargers.

FAQ
Does CYPD3174-16SXQT support USB PD 3.1 Programmable Power Supply (PPS)?
Yes. The device fully implements USB PD Revision 3.1, including PPS mode with 20-mV/50-mA resolution for dynamic voltage/current adjustment during charging. Firmware must be configured to expose PPS capabilities via the policy engine, and external FET drivers must support fast transient response.
What is the purpose of the bonded dead-battery RD resistors in this SOIC variant?
The CYPD3174-16SXQT has RD resistors physically bonded to CC1 and CC2 pins to ensure proper sink-role detection when the system battery is fully depleted. This enables cold-start functionality in power banks without requiring external pull-down resistors or auxiliary power sources.
Can CYPD3174-16SXQT regulate VBUS using optocoupler feedback?
Yes. The FB pin accepts isolated feedback signals from an optocoupler-based secondary-side regulation circuit. The internal shunt regulator and analog control loop maintain tight VBUS regulation across load and line variations without requiring external error amplifiers.
Is SWD debugging supported, and what debug resources are available?
Yes. The device includes a Serial Wire Debug (SWD) interface with four address breakpoint comparators and two data watchpoint comparators. This enables full firmware development, real-time variable inspection, and field firmware updates without requiring additional debug hardware beyond standard SWD probes.
