Product details
Overview
CYPD3174-16SXQ 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 sense amplifier - deployed in PC adapters, car chargers, and power banks.
For engineers reviewing the CYPD3174-16SXQ datasheet, CYPD3174-16SXQ pinout, CYPD3174-16SXQ application, or CYPD3174-16SXQ 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-based OVP/OCP/SCP protection on VBUS-connected pins.
Technical Context
The CYPD3174-16SXQ implements a dedicated USB PD 3.1 physical layer with BMC encoding, collision-avoidance half-duplex communication, and programmable RP/RD termination switching. Its two 8-bit SAR ADCs monitor VBUS, current sense voltage, and GPIO/DP/DM lines using internal bandgap or VDDD reference.
It integrates dual PFET gate drivers for VBUS path control, two VBUS discharge FETs, and a high-voltage regulator supporting 3.0–24.5 V input (30-V tolerant). The MCU subsystem includes SWD debug interface with four breakpoint and two watchpoint comparators, tightly coupled flash accelerator, and supervisory ROM boot routines.

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 thermal performance. | Required for dual-C-port designs (e.g., docking stations); lacks SOIC footprint compatibility. | Select when multi-port topology or higher power density is needed; not drop-in for SOIC PCBs. |
| STUSB4500QTR | Standalone USB PD 3.0 controller (no MCU); requires external microcontroller for PPS or custom policy engine. | Suitable for cost-sensitive single-port chargers where firmware flexibility is secondary to BOM simplicity. | Choose only if full PPS customization is unnecessary and external MCU resources are available. |
Compared with CYPD3174-16SXQ, the CYPD3175-24LQXQ offers dual-port scalability but sacrifices SOIC manufacturability, while the STUSB4500QTR reduces integration level and requires external firmware management - making CYPD3174-16SXQ optimal for single-port, space-constrained, and firmware-autonomous designs.

FAQ
Does CYPD3174-16SXQ support USB PD 3.1 Programmable Power Supply (PPS)?
Yes, CYPD3174-16SXQ fully supports USB PD 3.1 PPS mode with hardware-accelerated BMC decoding and sub-20-mV voltage step resolution. Its integrated Cortex-M0 executes the PPS policy engine, enabling real-time voltage/current adjustments without external host intervention.
What is the function of the DISCH pin?
The DISCH pin is an active-low output that controls the internal VBUS discharge FET. When asserted, it rapidly discharges VBUS through an integrated 10-Ω path, meeting USB-C specification requirements for ≤100-ms discharge time after disconnect or fault event.
Can CYPD3174-16SXQ operate without an external crystal?
Yes - it includes a factory-trimmed internal oscillator with ±2% accuracy across –40°C to +105°C, eliminating the need for external clock components. This oscillator drives the USB PD PHY, MCU core, and peripherals, reducing BOM count and board area.
How does the dead-battery RD resistor implementation differ between CYPD3174-16SXQ and CYPD3171?
CYPD3174-16SXQ features on-die RD resistors permanently bonded to CC1/CC2 pins for sink-mode operation, whereas CYPD3171 uses external pads for bond-wire configuration. This makes CYPD3174-16SXQ suitable for power banks requiring guaranteed dead-battery detection without assembly variation.
