CYPD3135-40LQXIT Overview
A USB Type-C port controller is a mixed-signal IC that implements the USB Type-C and USB PD specifications, detects cable orientation and attachment, negotiates PD contracts over the CC wire, and drives VBUS provider/consumer FETs. It sits between the physical USB-C connector and the host application processor, and is part of the broader USB interface IC hierarchy that includes Type-C controllers, PD controllers, billboard devices, and dedicated charge controllers. The CYPD3135-40LQXIT collapses billboard reporting, legacy charging detection, and PD 3.0 negotiation into one part.
Key features include USB PD 3.0 compliance, a billboard controller function, 2.7-21.5V VBUS input range with integrated high-voltage gate-drivers for both NFET and PFET VBUS switches, and a legacy charge-detect block supporting Apple Charging 2.4A, QC 4.0, and Samsung AFC. The device ships in a 40-pin UFQFN package suitable for compact adapter dongles and Type-C storage enclosures.
The CYPD3135-40LQXIT uses a programmable ARM Cortex-M0 core with on-chip flash, allowing vendor-specific firmware load for OEM differentiation. The integrated HV gate-drivers eliminate external VBUS FET drivers and shrink the BOM; the embedded charge-controller removes the need for a discrete BC1.2 chip. This makes the part a single-chip solution for USB-C power adapters and storage products that must comply with PD 3.0 and legacy charging protocols.
Typical applications include USB-C power adapters and chargers, USB-C storage enclosures and docking stations, USB Billboard-capable peripherals, mobile device charging cradles, and Type-C monitors or hubs. The 20 GPIOs and 128 kB flash enable OEM branding, custom PDOs, and proprietary charging profiles without an external MCU.
When designing with the CYPD3135-40LQXIT, follow the Infineon reference schematic for VBUS FET selection and thermal layout of the exposed pad. Validate against the USB-IF-CT3 USB PD 3.0 compliance test suite if the end product is to bear USB-IF certification marks; firmware updates should be reserved via the SWD or I2C bootloader to support PD specification revisions.

Typical Applications
CYPD3135-40LQXIT is suitable for 6 applications: USB-C Power Adapter / Charger, USB-C Storage Device / SSD Dongle, USB Billboard Device (Non-PD Peripheral), USB-C Docking Station, Type-C Monitor / Display, Mobile Charging Cradle / Accessory.
USB-C Power Adapter / Charger
The CYPD3135-40LQXIT is a drop-in PD controller for compact 45-65 W USB-C wall adapters and travel chargers. Its integrated 21.5 V-tolerant NFET/PFET gate drivers eliminate an external VBUS driver IC, while the ARM Cortex-M0 with 128 kB flash runs the full USB PD 3.0 stack plus vendor-specific charging profiles. Designers benefit from a single-chip solution that negotiates PD contracts on CC1/CC2, supports PPS, and reports via USB Billboard if the adapter is plugged into a non-PD host. Compared to discrete PD controllers, the CCG3 shrinks the BOM, simplifies EMI, and accelerates USB-IF-CT3 compliance testing for retail OEM adapters.

USB-C Storage Device / SSD Dongle
The CYPD3135-40LQXIT enables USB-C external SSDs and portable storage enclosures with USB 3.0 billboard reporting and PD 3.0 power negotiation. The 20 GPIOs handle drive status LEDs, write-protect switches, and user buttons, while 128 kB flash stores firmware for vendor-specific USB-C charging and billboard descriptors. The integrated legacy charge-detect block (Apple 2.4A, QC 4.0, Samsung AFC) lets the enclosure negotiate non-PD charging when connected to legacy hosts. The UFQFN-40 footprint keeps the controller footprint small, freeing PCB area for M.2 SSD sockets and power conversion stages.
Recommended
USB Billboard Device (Non-PD Peripheral)
When a non-PD device is connected to a USB-C host, the USB Billboard class is mandatory; the CYPD3135-40LQXIT integrates this Billboard controller to minimize BOM. Designers can use the same IC for legacy USB peripherals that need USB-C connectors but cannot fully implement USB PD, such as HDMI adapters, USB-C hubs, and DisplayPort alt-mode bridges. The device exposes standard Billboard descriptors and Vendor Specific Messages over USB 3.0. The Infineon reference firmware provides ready-to-customize descriptor templates.
Recommended
USB-C Docking Station
Docking stations and multi-port USB-C hubs use the CYPD3135-40LQXIT as the upstream PD contract negotiator and VBUS power manager. The integrated NFET/PFET gate drivers switch 100 W-class VBUS to downstream USB-C ports, while 20 GPIOs drive status indicators, button inputs, and downstream port enables. The 128 kB flash stores vendor-specific PDOs and dock-side PD policies. Designers can pair the CYPD3135-40LQXIT with an external USB 3.0 hub controller and DisplayPort multiplexer for full-featured docks.
Recommended
Type-C Monitor / Display
USB-C monitors that accept DisplayPort alt-mode input and deliver USB PD to upstream laptops use the CYPD3135-40LQXIT to negotiate the upstream power contract. The billboard controller reports capability mismatches when the monitor is plugged into a non-DP-capable host. The 128 kB flash stores monitor-side PDOs and DisplayPort alt-mode descriptors, while 20 GPIOs drive backlight, audio, and OSD controls. The compact UFQFN-40 footprint enables slim-panel designs where PCB real estate is at a premium.
Recommended
Mobile Charging Cradle / Accessory
Mobile charging cradles and accessories leverage the CYPD3135-40LQXIT's legacy charge-detect block to support Apple Charging 2.4A, QC 4.0, and Samsung AFC profiles. Designers can build universal cradles that negotiate the highest supported current from any modern smartphone, regardless of the OEM's proprietary protocol. The 20 GPIOs drive LED indicators, accessory buttons, and host-side detection. The UFQFN-40 package keeps the cradle PCB compact, while 128 kB of flash enables OTA firmware updates for newly-released charging protocols.

- USB Billboard controller integrated (vs Discrete billboard interface ICs)
Design Notes
The CYPD3135-40LQXIT is a UFQFN-40 6x6 mm part with a large exposed thermal/ground pad. The EP must be soldered to a continuous ground pour with at least 4 thermal vias to the inner GND layer. Insufficient ground stitching will degrade EMI performance on CC1/CC2 and may cause USB-IF-CT3 compliance failures. Use 4-layer stack-up with dedicated GND plane under the controller for best results.
Do not exceed the 21.5 V maximum VBUS input; over-voltage transients will damage the integrated NFET/PFET gate drivers. Add a TVS diode (e.g., 24 V SMBJ) on VBUS for hot-plug protection. Designers migrating firmware from CYPD3135-40LQXI prototypes to the LQXIT production reel must verify bootloader keys before commissioning production lines.
The CYPD3135-40LQXIT has separate VDD (digital I/O 3.3 V) and VCCD (regulated core supply) pins that require decoupling. Place 1 uF X7R 0402 ceramic capacitors close to each supply pin, with a 0.1 uF parallel capacitor for high-frequency noise. The integrated high-voltage gate drivers draw dynamic current during PD contract transitions; budget at least 50 mA of 3.3 V LDO headroom for the controller.
