Product details
Overview
CYPDC1185B2-32LQXQT from Cypress Semiconductor is an EZ-PD™ CCG3PA2 USB Type-C Port Controller with Arm® Cortex®-M0 core, dual 64-KB flash banks, integrated USB-PD 3.0 transceiver, on-chip VBUS regulation, and system-level ±8-kV contact ESD protection. It supports one Type-C port and one legacy Type-A port, delivers QC 4.0/Apple 2.4A/AFC/BC 1.2 charging, and operates across –40 °C to +105 °C in a 32-pin QFN package for power adapter and cable applications.
For engineers reviewing the CYPDC1185B2-32LQXQT datasheet, CYPDC1185B2-32LQXQT pinout, CYPDC1185B2-32LQXQT application, or CYPDC1185B2-32LQXQT equivalent, key selection criteria include USB PD3.0 compliance with PPS support, integrated low-side current sense amplifier (100 mA detection over 5 mΩ), dual PFET gate drivers for VBUS path control, and hardware OVP/OCP/SCP/UVP fault protection with configurable thresholds.
Technical Context
The CCG3PA2 implements a full USB PD3.0 physical layer with BMC encoding/decoding on CC lines, integrated RP/RD/RA resistors with firmware-controllable RA disconnect, and collision-avoidance half-duplex communication. Its analog feedback loop directly regulates secondary-side VBUS via cathode pin (FB/CATH) using either optocoupler or direct feedback topology.
It integrates two 8-bit SAR ADCs accessible across GPIO and DP/DM pins, two SCBs supporting I²C (up to 1 Mbps Fast Mode Plus), SPI, or UART with 8-deep FIFOs, and four TCPWM blocks enabling PWM-based VBUS discharge timing and charger signature detection. The MCU subsystem includes SWD debug interface with four breakpoint and two watchpoint comparators.

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB Type-C port controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STUSB4500QTR | Single 64 KB flash bank; no integrated CSA; requires external VBUS discharge FETs; supports PD3.0 but not PPS. | Limited to fixed-voltage adapters; lacks constant-current regulation capability for programmable power supplies. | Select when cost-sensitive designs require basic PD negotiation without PPS or precision current control. |
| TPS65987DRTJT | ARM M0+ core; dual 128 KB flash; integrated VBUS switch drivers; supports PD3.0 + PPS; no native BC 1.2/Apple/QC detection. | Requires companion charger ID IC for legacy charging; optimized for high-power dock/monitor applications over cable/adapter use cases. | Select for high-end docks needing >100 W delivery and advanced security features, accepting added BOM complexity for legacy charging. |

FAQ
Does CYPDC1185B2-32LQXQT support USB PD3.0 Programmable Power Supply (PPS)?
Yes, it fully supports USB PD3.0 v1.1 including PPS mode for dynamic voltage adjustment in 20 mV steps and current control in 50 mA steps. This enables precise power delivery for fast-charging smartphones and adaptive power supplies without external DACs or controllers.
What is the maximum VBUS voltage the device can withstand on CC pins during accidental shorts?
The CC1 and CC2 pins feature integrated VBUS short protection rated for continuous operation at ≤17 V and survival up to 22 VDC for 1000 hours. During transient ringing events, the on-chip ESD clamps limit peak voltage to ≤44 V, preventing latch-up or permanent damage.
Can the CCG3PA2 operate solely from VCONN without VBUS_IN or VDDD?
No. VCONN (3.0–5.5 V) is only a supplemental power source for EMCA cable applications and cannot power the full MCU subsystem. At least one primary supply-VBUS_IN (2.7–24.5 V) or VDDD (2.7–5.5 V)-must be present for functional operation.
How many GPIOs support overvoltage tolerance, and what is the rating?
Only GPIO pins P0.0 and P0.1 are overvoltage-tolerant (OVT) up to 7 V. All other GPIOs are referenced to VDDIO and must not exceed that supply voltage. This OVT capability allows safe interfacing with 5 V logic buses while the core runs at 3.3 V.
