Product details
Overview
CYPD3176-24LQXQ from Infineon is a pre-programmed USB Type-C sink port controller supporting up to 100 W power delivery, compliant with USB PD 3.1 v1.6 and programmable power supply (PPS) mode, integrated VBUS load switch gate drivers, and system-level ±8-kV contact/±15-kV air-gap ESD protection on CC/D+/D–/HPI pins - deployed in drones, smart speakers, and power tools replacing legacy barrel connectors.
For engineers reviewing the CYPD3176-24LQXQ datasheet, CYPD3176-24LQXQ pinout, CYPD3176-24LQXQ application, or CYPD3176-24LQXQ equivalent, key selection considerations include its dead-battery RD termination, VBUS short protection (17–22 V for 1000 h), SAFE_PWR_EN fallback to 5 V/900 mA, I2C slave address 0x08, and Cortex-M0-based firmware-updatable architecture.
Technical Context
The device implements a full USB PD 3.1 v1.6 sink policy engine with BMC-encoded half-duplex CC communication, hardware-enforced OVP/OCP (configurable thresholds), and VBUS-to-CC short protection using clamping diodes that suppress ringing up to 44 V. Its dead-battery RD resistor is bonded directly to both CC pins for unpowered role detection.
It integrates a 48 MHz Arm Cortex-M0 MCU (64 KB Flash, 8 KB SRAM), dual gate drivers (VBUS_FET_EN and SAFE_PWR_EN), VBUS discharge FETs for PD-spec timing compliance, and an I2C slave interface (0x08, Fast-mode Plus up to 1 Mbps) with open-drain GPIOs supporting 1.8 V/3.3 V I/O.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| USB PD Compliance | USB PD 3.1 v1.6 with PPS sink support - enables precise voltage/current negotiation for fast-charging applications. |
| Operating Voltage | 3.0 V to 24.5 V (30 V tolerant) - supports wide-input industrial power rails without external regulators. |
| ESD Protection | ±8 kV contact / ±15 kV air-gap (IEC61000-4-2 Level 4C) on CC, D+, D–, HPI_SDA/SCL - eliminates need for discrete TVS on critical signal lines. |
| VBUS Short Tolerance | Withstands 17 V continuously and 17–22 V for 1000 h on CC1/CC2 - prevents damage from accidental VBUS–CC shorts in compact USB-C connectors. |
| I2C Interface | Slave address 0x08, up to 1 Mbps (Fast-mode Plus), 1.8 V/3.3 V I/O compatible - enables direct connection to host MCUs without level shifters. |
| Temperature Range | –40°C to +105°C (extended industrial) - validated for operation in power tools and outdoor drone enclosures. |
| Firmware Update | Supported via I2C bootloader and SWD interface - allows field updates without redesigning hardware or adding debug headers. |
Pinout & Package
Supplied in a 24-pin QFN package (4 mm × 4 mm, 0.5 mm pitch) with exposed thermal pad, optimized for high-density PCB layouts and thermal dissipation in space-constrained portable devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CC1, CC2 | USB Type-C Configuration Channel | Bi-directional BMC data path with integrated RD termination and VBUS short protection - enables plug orientation detection and sink role establishment even during dead-battery conditions. |
| VBUS_IN_DIS | VBUS Input Discharge Control | Drives internal discharge FET to meet USB PD detach timing (<500 ms) - ensures safe VBUS ramp-down without external components. |
| VBUS_FET_EN | Primary Load Switch Gate Driver | Controls external PFET on VBUS sink path with soft-start - limits in-rush current during hot-plug events to prevent system brown-out. |
| SAFE_PWR_EN | Fallback Power Rail Gate Driver | Activates alternate PFET when negotiated PD contract fails - delivers 5 V/900 mA to maintain basic system operation (e.g., MCU boot, status LED). |
| HPI_SDA / HPI_SCL | I2C Host Processor Interface | Open-drain I2C slave bus (address 0x08) for configuration read/write and fault reporting - supports 1.8 V/3.3 V logic without level translation. |
| FAULT | Hardware Fault Indicator | Active-low open-drain output asserted on OVP/OCP event - signals host MCU to disable load switch and initiate recovery sequence. |
Key Features
| Feature | Design Value |
|---|---|
| Pre-programmed Sink Firmware | Ships with production-ready USB PD sink stack - eliminates firmware development effort and qualification time for barrel-connector replacement designs. |
| Legacy Charging Support | BC1.2, Apple, AFC, QC 2.0 detection - enables interoperability with non-PD wall adapters and older chargers without additional ICs. |
| Integrated Analog Monitoring | On-chip ADC measures VBUS_MIN/MAX and ISNK_COARSE/FINE - provides real-time telemetry for adaptive power management and safety logging. |
| System-Level ESD Integration | Full IEC61000-4-2 Level 4C protection on 7 pins (CC1/CC2, D+/D–, VBUS_IN_DIS, HPI_SDA/SCL) - reduces BOM count and layout area vs. discrete ESD arrays. |
| Thermal & Electrical Fault Handling | OVP/OCP response with FAULT assertion and HPI alert - enables coordinated system-level shutdown and recovery via host processor, not just local latch-off. |
Applications
| Drones (Portable UAVs) | Smart Speakers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB-C sink port controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CYPD3174-24LQXQ | Same die, no PPS support; fixed 5 V/9 V/15 V/20 V contracts only - lacks programmable voltage step control. | Suitable for cost-sensitive devices where PPS is unnecessary (e.g., basic speakers, LED lamps). | Select when PPS functionality is not required and BOM cost reduction is prioritized over future-proofing. |
| STUSB4500QTR | Standalone USB PD sink controller without integrated MCU or firmware - requires external host MCU for policy execution. | Used in systems with existing application processors capable of running PD stack (e.g., Linux-based gateways). | Choose when design already includes a capable host MCU and flexibility to customize PD behavior beyond pre-programmed profiles. |
Compared with CYPD3174-24LQXQ, this part adds PPS sink capability for tighter voltage regulation in fast-charging applications; versus STUSB4500QTR, it eliminates host MCU dependency and reduces firmware validation scope by shipping with certified, field-updatable sink firmware.

FAQ
Does CYPD3176-24LQXQ require external firmware development?
No. It ships with fully functional, pre-programmed USB PD sink firmware compliant with USB PD 3.1 v1.6 and PPS. Configuration changes (e.g., voltage/current limits, timeout values) are made via the EZ-PD™ Configuration Utility and written over I2C - no firmware coding or compilation is needed.
Can it operate without a host MCU?
Yes. It functions autonomously as a standalone sink controller with built-in policy engine, load switch control, and fault management. A host MCU is optional - used only for advanced telemetry, custom fault responses, or dynamic reconfiguration via HPI.
What is the purpose of the SAFE_PWR_EN pin?
SAFE_PWR_EN drives an external PFET to deliver 5 V/900 mA when the requested PD contract cannot be negotiated. This maintains basic system operation (e.g., MCU boot, display wake) while preventing complete power loss - critical for user-facing devices like smart speakers and medical monitors.
Is OTP (over-temperature protection) enabled by default?
No. OTP is disabled in the default firmware. It must be explicitly enabled using the EZ-PD™ Configuration Utility, and the FLIP pin must be repurposed as a thermistor input. This allows designers to opt in only when thermal monitoring is required for their specific mechanical layout and ambient conditions.
