Product details
Overview
CYPD3177-24LQXQT from Infineon Technologies (formerly Cypress) is a pre-programmed USB Type-C port controller IC for power sink applications, integrating USB PD 3.0 Revision 2.0 compliance, VBUS-to-CC short protection, on-chip OVP with configurable thresholds, and a load switch controller with soft-start. It operates from 3.0 V to 24.5 V, supports –40°C to +105°C, and targets barrel-connector-to-USB-C conversion in drones, smart speakers, and power tools.
For engineers reviewing the CYPD3177-24LQXQT datasheet, CYPD3177-24LQXQT pinout, CYPD3177-24LQXQT application, or CYPD3177-24LQXQT equivalent, key selection considerations include its dead-battery RD termination, SAFE_PWR_EN fallback logic, I²C slave interface (0x08, up to 1 Mbps), and integrated VBUS discharge FET meeting USB-PD detach timing.
Technical Context
The device implements a full USB PD 3.0 physical layer with BMC-encoded half-duplex CC communication, collision avoidance, and bonded dead-battery RD resistors on both CC pins for unpowered plug detection and orientation sensing. Its USB-PD subsystem includes hardware-based VBUS OVP (configurable threshold) and robust VBUS-to-CC short protection rated for 17 V continuous and 17–22 V for 1000 hours.
Power architecture uses VBUS_IN (3.0–24.5 V) to generate internal 3.3-V VDDD and 1.8-V VCCD rails; the SINK_FET_EN gate driver controls external PFETs with slew-rate control, while SAFE_PWR_EN activates a secondary 5-V/900-mA rail when higher-power contracts fail. The I²C interface (HPI_SDA/HPI_SCL) supports Fast-mode Plus but with 8-mA sink capability and relaxed fall-time compliance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB Type-C sink controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STUSB4500QTR | Supports USB PD 3.0 but lacks integrated VBUS discharge FET and SAFE_PWR_EN fallback logic; requires external components for detach timing and 5-V fallback | Targeted at cost-sensitive, lower-complexity sink designs without stringent detach-timing or dual-rail requirements | Select when BOM count is prioritized over autonomous fault recovery and USB-PD compliance completeness |
| TPS65987DRLR | Programmable PD controller with full firmware flexibility; requires external MCU, flash, and extensive validation; no dead-battery RD bonding | Used in high-end systems needing custom PD policies, alternate modes, or dynamic role swapping | Select only when pre-programmed operation is insufficient and engineering resources exist for full PD stack development |
Compared with STUSB4500QTR and TPS65987DRLR, CYPD3177-24LQXQT delivers turnkey USB-C sink functionality with zero firmware, hardened short protection, and guaranteed USB-PD detach compliance-reducing design risk and qualification effort for volume consumer and industrial devices.

FAQ
What is the function of the FLIP pin?
The FLIP pin is an open-drain output indicating USB Type-C plug orientation: pulled low for CC1 connection (unflipped) and high for CC2 (flipped). Its external pull-up resistor value (≤4.7 kΩ or 50 kΩ) determines whether the device reports itself as data-capable in the UFP Vendor Data Object, enabling or disabling USB 2.0 data negotiation capability.
Does CYPD3177-24LQXQT require external firmware programming?
No. It is factory-preprogrammed with a complete USB PD 3.0 sink stack and requires no firmware development, flash memory, or host processor intervention. Configuration is performed solely through resistor networks on VBUS_MIN, VBUS_MAX, ISNK_COARSE, and ISNK_FINE pins.
How does the SAFE_PWR_EN feature operate during power negotiation failure?
When the requested PD contract cannot be met, SAFE_PWR_EN activates a secondary PMOS gate driver to deliver 5 V at up to 900 mA through an alternate FET. This provides limited system operation-such as MCU boot or status indication-while maintaining safety isolation from the main VBUS path.
What is the purpose of the VBUS_MIN and VBUS_MAX pins?
These pins accept resistor dividers referenced to VDDD (3.3 V) to define the minimum and maximum acceptable input voltages from the power adapter. They directly configure the voltage range advertised in the Source Capabilities message during PD negotiation, ensuring the system only accepts compatible power contracts.
