What is a USB Type-C port controller? A USB-C port controller is a specialized mixed-signal IC that implements the USB Type-C and USB Power Delivery protocols over the USB-C configuration channel (CC) and data lines. It sits between a USB-C receptacle and a host MCU, negotiating voltage/current contracts with attached sinks and sources, controlling high-voltage VBUS MOSFETs via integrated gate drivers, and providing legacy charging handshakes. USB-C port controllers are members of the broader interface IC category (USB interface IC), bridging USB-C connectors to system power paths and embedded processors.
Key features of the CYPD3135-40LQXIES include an integrated high-voltage gate driver for NFET/PFET VBUS protection switches, a billboard-class controller capability, and on-chip legacy charge detection. The 20 GPIOs provide flexible mapping to status LEDs, push-button inputs, and external MOSFET controls. The 128 kB Flash supports USB PD 3.0 firmware with PPS (Programmable Power Supply) and HVDCP profiles.
The CCG3 family architecture combines an ARM Cortex-M0 subsystem, USB-PD physical layer, and high-voltage analog blocks on a single die, enabling notebook, monitor, and adapter OEMs to replace discrete Type-C interface logic with a single QFN-40 IC. The die is qualified to industrial-grade operating temperature and is halogen-free per Infineon product documentation.
Typical applications include notebook docking stations, USB-C monitors, travel adapters, USB-PD chargers, and Type-C power banks. The integrated gate driver eliminates external VBUS protection MOSFETs in many designs, reducing BOM cost and PCB area.
When designing with this device, observe the VBUS absolute maximum rating of 21.5 V and ensure the exposed pad is soldered to a sufficiently sized copper pour for thermal dissipation. Use Infineon's EZ-PD configuration tool and CCG3 firmware SDK to generate compliant USB PD 3.0 firmware.

典型應用
CYPD3135-40LQXIES 適用於 6 應用s: USB-C Power Adapter / Travel Charger, Notebook Docking Station, USB-C Monitor / Display, USB Power Bank / Portable Charger, Type-C Port Replicator / Hub, Industrial USB-C Embedded Module.
USB-C Power Adapter / Travel Charger
The CYPD3135-40LQXIES is engineered for USB-C travel adapters and wall chargers, where its 2.7-21.5 V VBUS tolerance and integrated high-voltage NFET/PFET gate drivers eliminate the need for an external LDO and protection circuitry. With USB PD 3.0 PPS support plus legacy charge detection (Apple 2.4A, QC 4.0, Samsung AFC), a single CYPD3135 negotiates optimal voltage/current contracts with attached phones, tablets, and laptops. The 128 kB Flash stores PDO/PPS tables for 5V/9V/12V/15V/20V outputs plus customizable vendor-defined messages. Designers pair it with a buck or flyback converter whose feedback the CYPD3135 can modulate via opto-isolator or I2C, achieving a complete USB-PD source solution in compact 30-65 W adapters.

Notebook Docking Station
The CYPD3135-40LQXIES serves as the upstream USB-C PD controller in notebook docking stations, where it negotiates 20 V / 5 A (100 W) PD contracts with the host laptop and manages downstream USB-C ports. Its 20 GPIOs drive status LEDs, button inputs, and VBUS protection MOSFETs on multiple USB-C downstream facing ports (DFPs). Per the Infineon CCG3 datasheet, the integrated high-voltage gate drivers and billboard class support enable docks that comply with USB-C alternate-mode requirements without a companion MCU. The 128 kB Flash accommodates full dock firmware including DisplayPort alt-mode entry/exit and USB 3.2 hub coordination.
推薦
USB-C Monitor / Display
USB-C monitors integrate the CYPD3135-40LQXIES to receive 65-100 W PD contracts from connected laptops while simultaneously outputting DisplayPort or HDMI video over the same cable. The device's integrated billboard support ensures the monitor can enumerate as a USB device when alt-mode negotiation fails, satisfying USB-IF compliance requirements. With 2.7-21.5 V VBUS tolerance, the CYPD3135 directly monitors VBUS for over-voltage and over-current events without external voltage dividers. The 20 GPIOs handle panel backlight control, USB-C cable orientation detection (CC1/CC2 swap), and downstream USB-A charging port control, all from a single UFQFN-40 IC.
推薦
USB Power Bank / Portable Charger
Portable USB-C power banks benefit from the CYPD3135-40LQXIES as a bidirectional PD controller - it negotiates variable-input contracts when charging from a wall adapter and outputs variable-voltage contracts to attached laptops. The wide 2.7-21.5 V VBUS range accommodates 1S to 4S lithium battery stacks with appropriate buck-boost conversion. The ARM Cortex-M0 core and 128 kB Flash allow battery-gauge algorithms to coexist with USB PD stack, eliminating an external MCU. Integrated legacy charge detection supports Apple 2.4A and Samsung AFC for fast-charging older smartphones without USB PD support.
推薦
Type-C Port Replicator / Hub
Multi-port USB-C hubs and port replicators use the CYPD3135-40LQXIES as a downstream-facing controller, replicating a host USB-C port across multiple downstream connectors. The integrated NFET/PFET gate drivers handle VBUS power-path switching and over-current protection for each downstream port without external MOSFETs, reducing BOM cost by 30-40%. Per the Infineon CCG3 datasheet, the 128 kB Flash supports DisplayPort 1.4 alt-mode entry/exit logic and USB 3.2 Gen 2 data-pass-through coordination. The exposed-pad UFQFN-40 package enables compact hub PCBs as small as 40x40 mm.
推薦
Industrial USB-C Embedded Module
Industrial equipment with USB-C service ports and programming interfaces use the CYPD3135-40LQXIES as a ruggedized PD controller. Its halogen-free UFQFN-40 package and RoHS compliance meet industrial environmental standards, while the integrated high-voltage gate drivers tolerate the noisy VBUS environments typical of factory equipment. The CCG3's ARM Cortex-M0 core allows field firmware updates over USB-C, simplifying service and calibration. Designers can implement deterministic USB PD contract negotiation for factory automation devices like PLCs, HMIs, and vision systems that require reliable USB-C connectivity under EMI-heavy conditions.

設計說明
The CYPD3135-40LQXIES in UFQFN-40 relies on the exposed pad (pin 40) for thermal dissipation. Per Infineon's layout guidelines, the EP must be soldered to a ground copper pour of at least 25 mm x 25 mm on the top layer, plus thermal vias (0.3 mm diameter, 1.0 mm pitch) to inner ground planes. Without adequate thermal conduction, VBUS gate-drive current spikes can cause junction-temperature rise above 100 C at sustained 21.5 V VBUS / 5 A conditions. Estimated: at 3 W typical dissipation with 30 C/W theta-JA on a 4-layer 1 oz PCB, junction rise is approximately 90 C above ambient.
Place the CYPD3135-40LQXIES decoupling capacitor (1 uF X7R) within 2 mm of the VDDD/VDDIO pins. The CC1/CC2 pull-up/pull-down reference resistors must be placed adjacent to the respective CC pins; do not route CC traces over ground plane splits, as USB-C attach/detach detection relies on clean CC signaling. The VBUS sense pin traces should be Kelvin-connected to the USB-C receptacle VBUS pad to avoid IR-drop-induced false over-voltage triggers.
Do not exceed VBUS absolute maximum of 24 V even transiently - add a TVS diode (e.g., SMAJ24CA) at the VBUS input for hot-plug surge protection. Per Infineon's CCG3 datasheet, VBUS below 2.7 V will cause the device to enter reset and drop the PD contract, which can cause downstream devices to brown-out during startup. The SWDIO/SWDCK pins are 5 V tolerant but should not be driven above 5.5 V; use a 4.7 kOhm pull-up on SWDIO for ARM SWD debug.
