CYPD3135-40LQXQ - EZ-PD CCG3 USB Type-C PD Controller | Infineon
MPN: CYPD3135-40LQXQ ✓ Hoạt độngCYPD3135-40LQXQ Tóm tắt
Background - What is a USB Type-C Port Controller? A USB Type-C port controller is an Application Specific Standard Product (ASSP) that manages the Configuration Channel (CC) lines, USB-PD protocol messaging, VBUS detection, and Alternate Mode entry on a Type-C port. It sits between the USB-C connector and the host system processor (or power supply controller), handling the USB-PD 3.0 state machine so the application processor does not need to implement the entire USB-PD protocol stack. The CYPD3135 belongs to Infineon's EZ-PD CCG3 family, which is a hypernym under USB-PD controllers -> interface ICs -> integrated circuits.
Key features of the CYPD3135-40LQXQ include: 48 MHz ARM Cortex-M0 with 128 KB flash and 8 KB SRAM for firmware customization; 20 GPIOs for connector orientation detection, fault signaling, and VBUS discharge control; integrated VBUS-to-CC short protection; USB-PD 3.0 including Programmable Power Supply (PPS) support; and an industrial temperature grade suitable for power adapters and docking stations. The 40-pin UFQFN exposed-pad package improves thermal dissipation for high-current source applications.
Technical depth - The CYPD3135 implements the USB Type-C Cable and Connector specification including CC1/CC2 5.1 kohm pull-up/pull-down detection, and integrates a BMC (Biphase Mark Coding) transceiver for USB-PD messaging on the CC line. The on-chip PHY supports USB-PD up to 1 Mb/s communication and Source/Sink/Dual-Role Power (DRP) roles. With 128 KB flash, the device can be field-upgraded for the latest PD revisions or vendor-specific messaging.
Typical applications include USB-C power adapters (18 W to 100 W), USB-PD chargers for notebooks and tablets, USB-C hubs, docking stations, monitor power-in jacks, and Type-C audio adapters. The wide operating voltage supports source applications where VBUS can reach 21.5 V during high-power contract.
Design consideration - Ensure adequate PCB copper under the exposed pad for thermal relief and connect CC1/CC2 pins directly to the Type-C receptacle with no series resistance. Add TVS protection on CC lines if the design must survive ESD events above IEC 61000-4-2 8 kV contact.

Ứng dụng tiêu biểu
CYPD3135-40LQXQ phù hợp cho 6 Áp dụngs: USB-C Power Adapter (18 W to 65 W), Notebook and Tablet USB-C Charger, USB-C Hub and Docking Station, USB-C Monitor Power Input, USB-C Audio Adapter and Dongle, Industrial IoT Type-C Power/Data Port.
USB-C Power Adapter (18 W to 65 W)
The CYPD3135-40LQXQ's USB-PD 3.0 with PPS support and 1 Mb/s BMC PHY make it ideal for 18 W to 65 W USB-C power adapters where source-side role negotiation on the CC lines drives the flyback or PFC + LLC controller. The 128 KB flash allows manufacturer-specific VID/PID and PPS voltage steps from 3.3 V to 21 V for fast-charge smartphone protocols. Placed between the Type-C receptacle and the secondary-side regulation loop, the CYPD3135 negotiates the PD contract via CC1/CC2 and provides VBUS discharge / OVP signaling to the PFC controller; the 40-UFQFN exposed pad dissipates gate-drive switching losses comfortably at room temperature.

Notebook and Tablet USB-C Charger
For 45 W to 100 W notebook and tablet USB-C chargers, the CYPD3135-40LQXQ's PPS support enables fine-grained voltage steps required by modern fast-charge protocols (USB PD 3.0 + QC + BC1.2) on a single Type-C port. The 48 MHz ARM Cortex-M0 with 128 KB flash runs Infineon's EZ-PD firmware stack and can be re-flashed to support new PD revisions. Used between the Type-C connector and PFC controller, it provides safe CC line handling (5.1 kohm pull-up/down) and VBUS discharge on unplug, critical for 20 V contracts where stored cable capacitance can damage downstream ports.

USB-C Hub and Docking Station
The CYPD3135-40LQXQ's 20 GPIOs and integrated VBUS-to-CC short protection make it well-suited for USB-C hubs and docking stations that must negotiate multiple downstream PD roles and provide robust fault isolation. The 8 KB SRAM supports structured vendor-defined messages (VDMs) for Alternate Mode entry (DisplayPort, Thunderbolt signaling), and the 128 KB flash carries hub-specific policy such as billboard device descriptors. Placed at each Type-C port of the hub, it sources or sinks power per the negotiated contract; compared to discrete CC logic + external MCU, the CCG3 eliminates a 25-30 component BOM.

USB-C Monitor Power Input
USB-C monitors receiving 60 W to 90 W PD power use the CYPD3135-40LQXQ as the front-end controller to negotiate the power contract before the internal DC-DC block converts to the monitor's logic rails. The 21.5 V VBUS rating covers standard 20 V PD contracts, and the exposed-pad 40-UFQFN enables compact placement behind the Type-C jack with adequate thermal relief. The on-chip Cortex-M0 handles monitor-specific Extended Message Range and vendor-defined messages for monitor-side authentication; designers can field-upgrade via the flash for newer PD specs.

USB-C Audio Adapter and Dongle
USB-C audio adapters that pull 5 V/1.5 A or 9 V/2 A from a Type-C source use the CYPD3135-40LQXQ's source role capability to negotiate a stable PD contract and drive an integrated headphone codec. The 20 GPIOs interface to analog mute switches and mode-selection buttons without an external GPIO expander. With 128 KB flash, designers embed product-specific USB Billboard descriptors and vendor messages for legacy device emulation when the host refuses Alternate Mode entry. The compact 40-UFQFN package fits behind a Type-C jack on cable ends and dongle housings.

Industrial IoT Type-C Power/Data Port
Industrial IoT gateways and edge nodes using USB-C for both 5 V to 20 V power input and data connection rely on the CYPD3135-40LQXQ's industrial-grade behavior to survive extended thermal ranges and field vibration. The device integrates CC line protection up to 21.5 V VBUS, easing TVS selection on industrial USB-C ports. The 128 KB flash stores secure-boot firmware and vendor-defined messages for OEM authentication; the exposed-pad 40-UFQFN improves thermal performance in sealed enclosures where ambient can reach 60-70 C. Designers can implement DRP (Dual-Role Power) so a single port sources or sinks power depending on attached device role.

Ghi chú thiết kế
Route CC1 and CC2 traces from the connector to the CYPD3305 device using a 0.2-0.3 mm wide trace, kept short (<10 mm) and matched in length (within 0.5 mm) to preserve signal integrity. Avoid running CC traces parallel to or under noisy VBUS or switching converter traces; cross at 90 degrees if crossing is unavoidable. Place the 100 nF decoupling cap for VDD as close to the VDD pin as possible, with a star-delta to a low-impedance ground pour.
Solder the exposed pad (EP) of the 40-UFQFN package to a copper pour of at least 25 mm x 25 mm on the top and inner layers, stitched with thermal vias (0.3 mm drill, 0.6 mm pitch) to inner copper. Estimated: at 5 V VBUS source role and typical 1.5 W port dissipation, the junction temperature rise is ~30 C above ambient with the recommended copper area, allowing reliable operation in sealed enclosures up to 60 C ambient.
Do not connect CC1 or CC2 directly to VBUS without proper Rp/Rd pull-up/pull-down resistors - the CYPD3135 integrates these internally but the external pin must be connected only to the Type-C receptacle, never to VBUS. Always add IEC 61000-4-2 ESD TVS diodes (working voltage >=24 V) on CC1, CC2, DPLUS, and DMINUS to survive 8 kV contact ESD events. Ensure the firmware image in the 128 KB flash is signed and the secure-boot bit is set for production builds.
Keep the VBUS_SENSE trace away from switching nodes and route it directly to the Type-C VBUS pin through a 100kohm/100kohm resistor divider if monitoring high-voltage rails. Place the VBUS_DISCHARGE MOSFET close to the connector so discharge current flows through a low-inductance path. Use a 4-layer PCB with a continuous GND plane on layer 2 directly under the CYPD3135 to minimize EMI coupling into CC lines.
