概述

Description

CYPD4125-40LQXIT is a Cypress (Infineon) USB Type-C Port Controller with USB Power Delivery support used to implement PD-enabled USB-C ports in devices such as chargers, adapters, docks, and laptops.
What it does:
- Negotiates USB PD contracts and controls VBUS on a USB-C port
- Manages CC1/CC2 lines, cable orientation, and role negotiation
- Provides protections (OVP, UVLO, OCP, short-circuit, thermal) and dead-battery support
- Offers an MCU interface (I2C/SPI) for configuration and status
Typical applications:
- USB-C wall chargers, power banks, docking stations, and portable electronics requiring PD
Key benefits:
- Integrated PD controller and VBUS switch, reducing external components
- Compact footprint with robust protection and fast PD negotiation
Note: For exact electrical specs (PD revision supported, current/voltage ranges, interface details), consult the official CYPD4125-40LQXIT datasheet.

Features

CYPD4125-40LQXIT is a Cypress/Infineon EZ-PD USB Type-C Port Controller. Key features include:
- USB Type-C port controller with PD engine and dual-role port (DRP) capability
- USB PD 2.0/3.0 compliant; supports power role swap and contract negotiation
- I2C (or similar) control interface for configuration and status
- Integrated VBUS switch with programmable current limit and fault protection
- VCONN support and CC line cable orientation/detection
- VBUS discharge path when turning off the port
- Dead-battery support and fast wake for power delivery
- Protection features: overcurrent, overvoltage, short-circuit, thermal shutdown
- ESD protection on USB-C lines
- 40-pin LQFP packaging (40LQXIT)
Note: For exact electrical specs (current limit, PD profiles, timing, and pinout), consult the latest datasheet.

Package

It comes in a 40-pin LQFP (LQX) package, Industrial Temperature (IT) variant.

Pinout

- Pin count: 40 pins
- Function: USB Type-C Port Controller with Power Delivery (PD) negotiation and CC logic for USB-C port management (external FETs typically required).

Manufacturer

- Manufacturer: Cypress Semiconductor Corporation (now part of Infineon Technologies).
- What kind of company: A multinational semiconductor company that designs and manufactures integrated circuits and embedded solutions (e.g., microcontrollers, memory, USB/PD controllers).

Application

Main application areas: USB-C Power Delivery controllers for PD negotiation in Type-C devices; used in wall/portable chargers and power banks, docking stations and USB-C hubs, PD-enabled display adapters and monitors, notebook/tablet/phone chargers, and embedded power-management for consumer electronics and PD accessories.
