Product details
Overview
CYPD3175-24LQXQT 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 CYPD3175-24LQXQT datasheet, CYPD3175-24LQXQT pinout, CYPD3175-24LQXQT application, or CYPD3175-24LQXQT equivalent, key selection criteria include VBUS short protection on CC pins, dead-battery RD bond option for power bank sink role, integrated shunt regulator for opto-coupled feedback, and 24-pin QFN package with –40°C to +105°C operation.
Technical Context
The device implements a BMC-encoded USB PD 3.1 physical layer with hardware collision avoidance, configurable RP/RD termination, and dedicated dead-battery RD bonding for power bank applications. Its two 8-bit SAR ADCs support GPIO/DP/DM voltage sensing with internal bandgap or VDDD reference.
VBUS regulation uses analog feedback control with direct or opto-coupler interface, supporting constant-voltage and constant-current modes via integrated shunt regulator and low-side current sense amplifier. Integrated PFET gate drivers and VBUS discharge FETs enable full secondary-side power path control without external discrete components.

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 dead-battery RD bond option; same MCU and PD 3.1 feature set. | Targeted at space-constrained but non-power-bank applications (e.g., wall chargers without sink capability). | Select when board area is critical and sink-mode dead-battery operation is unnecessary. |
| STUSB4500QTR | Standalone PD controller (no MCU); requires external microcontroller for policy engine; no legacy charger detection. | Suitable only for simple DFP-only applications where firmware customization is handled externally. | Choose only if existing MCU handles PD policy and legacy charging is not required. |
Compared with CYPD3174-16SXQ, CYPD3175-24LQXQT adds dead-battery RD bonding and QFN thermal performance; versus STUSB4500QTR, it delivers full embedded PD+legacy charging autonomy without external firmware dependency.

FAQ
What is the function of the VBUS_C_MON_DISCHARGE pin?
This pin monitors VBUS voltage through an external resistor divider and triggers the integrated discharge FET when the port is disabled or during fault conditions. It provides active VBUS discharge down to <2.5 V within 100 ms, meeting USB-C specification requirements for safe hot-plug removal and preventing residual voltage hazards.
Does CYPD3175-24LQXQT support dual-role port (DRP) operation?
Yes - it supports DRP via firmware-controlled role swap using the integrated PD 3.1 stack. The device dynamically toggles between DFP and UFP roles based on CC line state, VCONN negotiation, and policy engine decisions, with hardware-assisted BMC timing and collision avoidance for reliable bidirectional communication.
How is dead-battery charging enabled on this part?
Dead-battery charging is enabled by factory-bonded RD resistors directly on CC1 and CC2 pins - a hardware-level configuration unique to CYPD3175 variants designated for power bank sink applications. This allows the port to present valid sink terminations even when VDDD is unpowered, enabling charging from hosts with zero-battery voltage.
Can the integrated ADC measure VBUS voltage directly?
No - the ADC inputs are limited to VDDIO (3.3 V) maximum. To measure VBUS, an external resistor divider must scale VBUS to ≤3.3 V before connecting to a GPIO or dedicated ADC input pin. The device includes no high-voltage ADC channel; all analog sensing requires proper scaling and clamping per datasheet Section 6.4.5.
