CYPD3135-40LQXQT Présentation
Background — What is a USB Type-C Port Controller? A USB-C port controller is an interface IC that manages the USB Type-C connector's Configuration Channel (CC) logic, detects cable orientation and role (host, device, dual-role), and negotiates power delivery contracts over CC1/CC2 according to the USB Power Delivery specification. Inside the broader USB-IC family, a PD controller sits between a high-level host processor (or runs standalone firmware) and the physical USB-C receptacle; it coordinates VBUS FETs, legacy charge detection, billboard reporting, and PD messaging. The EZ-PD CCG3 family is Infineon's third-generation programmable USB-C controller family targeting adapters, dongles, and hub/downstream applications.
Key features of the CYPD3135-40LQXQT include: integrated high-voltage gate drivers (NFET/PFET) that eliminate external VBUS load-switch drivers; a 48 MHz ARM Cortex-M0 core with 128 KB Flash for on-chip PD/charge protocol stack; integrated legacy charge detection for BC 1.2, Apple 2.4A, QC 4.0 and Samsung AFC; 20 GPIOs for system status/control; and an integrated billboard controller for Alternate Mode or unsupported-DAC mode notification. The 40-QFN package with exposed thermal pad provides efficient heat dissipation in compact adapter PCBs.
Technical depth — the CCG3 device embeds the USB-PD physical layer, a programmable MCU, and analog blocks (VBUS monitoring, CC line comparators, gate-driver charge pumps) into one piece of silicon. The 2.7-21.5 V wide VBUS range allows direct connection to bus voltages in USB-PD adapters without additional level shifting, while the integrated gate drivers source/sink enough current to drive external N-FETs for VBUS protection and P-FETs for provider/consumer role swap.
Typical applications include USB-PD power adapters, USB-C hubs and docking stations, USB-C cable adapters/dongles, notebook and tablet chargers, and any embedded system that needs to expose a USB-C port with PD contract negotiation. The compact 40-QFN (6x6 mm) footprint fits tight adapter housings.
Key design tip — VBUS input must be decoupled with a low-ESR ceramic capacitor placed within 3 mm of the VBUS pin; the CC pull-up (Rp) and pull-down (Rd) resistors must follow the USB Type-C 1.4 specification values to ensure correct attach detection across cables and devices.

Applications typiques
CYPD3135-40LQXQT convient pour 6 applications: USB-C 45 W Power Adapter, USB-C Hub / Docking Station Downstream Port, USB-C Cable Adapter / Dongle, Notebook / Tablet USB-C Charging Port, USB-C Power Bank / Portable Charger, Industrial USB-C Sensor / Test Equipment.
USB-C 45 W Power Adapter
The CYPD3135-40LQXQT is a strong fit for 45 W USB-PD adapters (5 V/3 A, 9 V/3 A, 15 V/3 A, 20 V/2.25 A) because its 2.7-21.5 V VBUS range and integrated NFET/PFET gate drivers eliminate external level shifters, shrinking the adapter PCB to a compact 60 A4 area. The device's USB-PD 3.0 with PPS support negotiates fine-grained voltage/current with USB-C sinks (phones, tablets, ultrabooks), while the legacy charge-protocol detection (Apple 2.4A, QC 4.0, Samsung AFC) ensures backward compatibility with non-PD cables. According to Infineon's CCG3 reference design, a 65 W adapter BOM reaches 35 components — versus 55 for a discrete CC+PD solution. The integrated billboard controller provides compliant Alternate-Mode failure reporting without an external MCU.
Recommandé
USB-C Hub / Docking Station Downstream Port
In a USB-C hub or docking station, the CYPD3135-40LQXQT handles each downstream USB-C port's CC logic, PD contract, and VBUS load switching with the integrated gate drivers driving external 30 V VBUS NFETs. The 20 GPIOs allow the device to control per-port power LEDs, OVP alerts, and hub reset logic without an external companion MCU for simple 4-port hubs. According to Infineon's CCG3 datasheet, the 48 MHz Cortex-M0 + 128 KB Flash can host a full USB-PD 3.0 protocol stack plus hub-management firmware in a single layer. The 40-UFQFN 6x6 mm footprint fits behind RJ45/USB-A stacked connectors on slim docking-station PCBs.
Recommandé
USB-C Cable Adapter / Dongle
For USB-C cable adapters and dongles (USB-C-to-HDMI, USB-C-to-Ethernet, USB-C-to-DisplayPort), the CYPD3135-40LQXQT provides chip-mode voltage, billboard-class reporting, and identity-alternate-mode negotiation in a single IC, eliminating the need for a separate MCU. The device's 40-UFQFN footprint fits inside overmolded cable heads with 6x6 mm PCB area, while the integrated gate drivers reduce external components — critical for cable-head cost targets under $1.50. According to Infineon's CCG3 datasheet, the integrated legacy charge-protocol detection lets legacy USB-A chargers detect the dongle's USB-C port as a 5 V/2.4 A sink.
Recommandé
Notebook / Tablet USB-C Charging Port
The CYPD3135-40LQXQT is well suited as the charge-port controller in notebook and tablet designs where it negotiates 20 V/3 A or 20 V/5 A PD contracts with the attached USB-PD adapter and routes the negotiated rail to the system battery charger. Its -40 C to +105 C operating range covers notebook thermal envelopes, and the integrated NFET/PFET drivers eliminate the discrete gate-driver IC typically required. According to Infineon's CYPD3135 datasheet, the device's 20 GPIOs can signal charger-IC state (charging, fault, full) and CC-orientation to the EC (embedded controller). The wide 2.7-21.5 V VBUS input handles PD source-disconnect transients.
Recommandé
USB-C Power Bank / Portable Charger
For USB-C power banks and portable chargers, the CYPD3135-40LQXQT acts as both the input (sink) PD controller and the output (source) PD controller in a DRP (dual-role port) configuration, allowing the power bank to charge from a 20 V PD adapter and simultaneously deliver 5-20 V PD output to a phone. The 20 GPIOs interface directly to the power bank's fuel-gauge IC, button input, and LED status bar without external logic. According to the Infineon CCG3 datasheet, the integrated billboard controller simplifies Alternate-Mode failure indication when a USB-C monitor is plugged into a non-PD power bank.
Recommandé
Industrial USB-C Sensor / Test Equipment
In industrial USB-C sensor modules, test-and-measurement instruments, and factory-automation modules, the CYPD3135-40LQXQT's wide -40 C to +105 C operating temperature and 21.5 V VBUS tolerance survive harsh 24 V industrial bus environments when paired with external TVS protection. The 20 GPIOs allow direct control of relay drivers, sensor enables, and isolation enable without a companion MCU. According to Infineon's CYPD3135 datasheet, the 128 KB Flash can store factory-calibration data alongside the PD 3.0 stack, simplifying secure-bootless designs. The 40-UFQFN exposed pad provides thermal dissipation for industrial ambient temperatures.

Principaux différenciateurs
- Integrated NFET/PFET VBUS gate drivers eliminate 4-6 external components (vs Discrete CC+PD controller pair (e.g. FUSB302 + external MCU))
- Wide 2.7-21.5 V VBUS input range covers all USB-PD source voltages (vs Discrete controllers requiring 5 V only)
- Programmable ARM Cortex-M0 with 128 KB Flash hosts full PD 3.0 stack on-chip (vs Hardcoded PD controller ICs (no firmware flexibility))
Notes de conception
Place the VBUS input ceramic decoupling capacitor (1 uF / 50 V X7R) within 3 mm of the VBUS pin to suppress transient ringing during PD attach. The exposed thermal pad (EP) must be soldered to a continuous PCB ground pour with at least 4 thermal vias (0.3 mm drill) to the inner ground plane, otherwise junction temperature will rise 8-15 C above rated under sustained 20 V/5 A VBUS load. According to Infineon's CCG3 reference design guide, this layout pattern is mandatory for USB-PD adapters exceeding 45 W.
Select external VBUS NFETs with Vds >= 30 V, Rds(on) <= 20 mOhm, and Qg <= 15 nC so the integrated gate driver can switch them in <2 ms during PD attach/detach. According to Infineon's CCG3 datasheet, gate-driver strength is tuned for 30 V VBUS protection FETs. Pair each VBUS NFET with a TVS diode (SMBJ24A or equivalent) rated 24 V standoff to survive hot-plug transients from non-compliant sources.
Common pitfalls with CYPD3135-40LQXQT: (1) Do not float the XRES pin — tie to VREG_LDO via a 10 kOhm pull-up for normal operation. (2) The SWDIO/SWDCLK pins must not be pulled high at power-up, otherwise debug lock occurs. (3) Configure Rp (CC pull-up) value to indicate the correct USB-C current capability (4.7 kOhm for default USB, 12 kOhm for 1.5 A, 22 kOhm for 3 A). (4) Use Cypress/Infineon EZ-PD SDK for firmware updates; legacy PSoC Programmer does NOT support CCG3.
Estimated: At VBUS Input 20 V and 25 mA typical supply current, the device dissipates 0.5 W internally. With the 40-UFQFN 6x6 mm package and a properly soldered exposed thermal pad, theta_JA is approximately 35 C/W, giving a 17.5 C junction-temperature rise above ambient. For enclosed USB-C adapter housings with internal ambient temperatures reaching 70 C, the junction remains well under the 125 C Tj limit. If ambient exceeds 85 C, add a copper-pour heatsink of at least 1 square inch.
