Product details
Overview
CYPD3176-24LQXQT from Infineon is a pre-programmed USB Type-C sink port controller supporting up to 100W 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 barrel connectors.
For engineers reviewing the CYPD3176-24LQXQT datasheet, CYPD3176-24LQXQT pinout, CYPD3176-24LQXQT application, or CYPD3176-24LQXQT equivalent, key selection criteria include USB PD 3.1 sink negotiation capability, RD termination for dead-battery detection, SAFE_PWR_EN fallback control, VBUS short protection up to 22 V on CC pins, and I2C slave interface (0x08, Fast-mode Plus) for host processor integration.
Technical Context
The device implements a dual-role USB PD physical layer with BMC-encoded half-duplex communication over CC lines, including bonded dead-battery RD resistors on both CC1/CC2 for plug orientation and UFP role detection without external bias. Its hardware-based OVP/OCP protection triggers FAULT assertion and HPI alerts, while VBUS discharge FETs meet USB-PD detach timing requirements.
It integrates an Arm Cortex-M0 MCU (48 MHz, 64 KB Flash, 8 KB SRAM) running pre-loaded firmware, with SWD and I2C bootloader support; the SCB operates as an I2C slave (0x08) at up to 1 Mbps, featuring open-drain I/Os compatible with 1.8 V/3.3 V hosts but with 8 mA IOL (not full Fast-mode Plus spec).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| USB PD Spec Support | USB PD 3.1 v1.6 with PPS sink mode - enables precise 20 mV-step voltage control for battery charging efficiency |
| VBUS Operating Range | 3.0 V to 24.5 V (30 V tolerant) - supports wide-input legacy adapters and USB-C PD sources |
| ESD Protection | ±8 kV contact / ±15 kV air-gap (IEC61000-4-2 Level 4C) on CC, D+, D–, HPI_SDA/SCL - eliminates need for external TVS diodes |
| I2C Interface | Slave address 0x08, up to 1 Mbps (Fast-mode Plus), 1.8 V/3.3 V IO-compatible - enables direct connection to common microcontrollers |
| Load Switch Control | Integrated gate drivers for external PFETs with soft-start - limits in-rush current during hot-plug to prevent system brown-out |
| Temperature Range | –40°C to +105°C (industrial grade) - validated for power tools and outdoor drone operation |
| VBUS Short Protection | Withstands 17 V continuously and 17–22 V for 1000 hrs on CC pins - prevents damage from USB-C connector layout-induced VBUS-to-CC shorts |
Pinout & Package
Supplied in a 24-pin QFN package (4 mm × 4 mm, 0.5 mm pitch, exposed thermal pad), RoHS-compliant and moisture-sensitive level 3 (MSL3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CC1, CC2 | USB Type-C Configuration Channel | Bi-directional BMC data path with bonded RD for sink detection; includes VBUS short protection and IEC61000-4-2 ESD clamping |
| VBUS_IN_DIS | VBUS Input Discharge Enable | Active-low signal controlling internal VBUS discharge FET to meet USB-PD detach timing (≤1 s) |
| SAFE_PWR_EN | Fallback Power Rail Gate Driver | Drives external FET to deliver 5 V/900 mA when negotiated PD contract fails - enables limited-system operation |
| VBUS_FET_EN | Sink Load Switch Gate Driver | Controls external PFET on VBUS path with programmable soft-start slope to limit in-rush current |
| HPI_SDA / HPI_SCL | I2C Host Processor Interface | Open-drain I2C slave bus (address 0x08) for configuration updates and real-time fault reporting |
| FAULT | Hardware Fault Indicator | Open-drain output asserted low on OVP/OCP event - signals host to disable power path and initiate recovery |
Key Features
| Feature | Design Value |
|---|---|
| Pre-programmed PD Sink Firmware | Ships ready-to-deploy with USB PD 3.1 sink stack, RD termination, and PPS support - zero firmware development required |
| Legacy Charging Compatibility | Detects BC1.2, Apple, AFC, QC2.0 (license required) on USB-A ports - maintains backward compatibility during transition to USB-C |
| System-Level Fault Protection | Hardware OVP/OCP/OTP monitoring with FAULT pin assertion and HPI alert - enables deterministic failure response without MCU intervention |
| Voltage Tolerance & Robustness | 30 V absolute max on VBUS pins and 22 V short-tolerance on CC - survives miswiring and transient overvoltage in industrial environments |
| Thermal & Power Management | Integrated OTP sensing (enabled via FLIP pin reconfiguration) and high-voltage regulator - reduces BOM count and PCB area vs discrete solutions |

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 |
|---|---|---|---|
| CYPD3171-24LQXQ | Lacks PPS support and has reduced VBUS tolerance (20 V max); no SAFE_PWR_EN pin | Suitable only for fixed 5/9/15/20 V contracts; no fallback power rail capability | Select when PPS and 5 V fallback are not required - lower cost for basic USB-C sink designs |
| STUSB4500QTR | Standalone PD sink controller without integrated MCU; requires external firmware; no legacy charging protocol support | Needs external microcontroller for BC1.2/AFC/QC handling; no pre-programmed firmware | Select when full firmware customization is needed and legacy charging is handled elsewhere in system |
Compared with CYPD3176-24LQXQT, CYPD3171-24LQXQ omits PPS and SAFE_PWR_EN - limiting dynamic charging and fail-safe operation; STUSB4500QTR shifts firmware burden to host MCU and excludes legacy charging - increasing design complexity and BOM count for multi-protocol systems.

FAQ
Does CYPD3176-24LQXQT require external firmware development?
No. It ships with fully functional, pre-programmed USB PD 3.1 sink firmware supporting PPS, RD termination, and legacy charging protocols. 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 SWD debugging is needed for standard use cases.
What is the purpose of the SAFE_PWR_EN pin?
SAFE_PWR_EN is an active-high gate driver that enables an external FET to deliver 5 V/900 mA when the requested PD power contract cannot be negotiated. This allows the host system to enter a low-power operational mode instead of failing entirely - critical for user-facing devices like smart speakers needing graceful degradation.
Can CYPD3176-24LQXQT support Apple or QC2.0 charging from USB-A ports?
Yes - it detects BC1.2, Apple 2.4 A, AFC, and QC2.0 protocols on non-USB-C (e.g., USB-A) upstream sources. However, customers must obtain separate licensing agreements directly from Qualcomm and Apple to legally implement QC2.0 and Apple charging; Infineon provides the detection logic only.
Is external ESD protection required on CC or D+/D– lines?
No. The device integrates full IEC61000-4-2 Level 4C ESD protection (±8 kV contact, ±15 kV air-gap) on CC1, CC2, D+, D–, HPI_SDA, and HPI_SCL pins. This eliminates the need for external TVS diodes in most layouts, reducing BOM count and board space while ensuring robust field reliability.
