Overview

The MCP22350-1I/Q8X is a USB Type-C Power Delivery (PD) port controller designed to handle the complex signaling required for modern USB power negotiation. It operates as a bridge between an SPI host and the USB interface, managing power profiles and Fast Role Swap (FRS) functionality while maintaining a low-power footprint. This specific variant comes in a compact 28-QFN package and is rated for industrial temperature ranges from -40C to 85C.

Why Choose This Part

This controller supports multiple low-power modes including Hibernation and Standby (1200 uA) to maximize efficiency in battery-powered applications. It features 8 GPIO pins and an integrated watchdog timer, reducing the component count required for peripheral management in space-constrained 4x4 mm designs.

Applications

USB-C Power Delivery Infrastructure
Managing power profiles for docking stations and wall adapters to ensure safe and efficient high-wattage charging.
Industrial Equipment Power Bricks
Integrating USB PD into industrial machinery for standardized power input and data diagnostic capabilities.
Consumer Electronics Charging Ports
Providing Type-C connectivity for portable devices that require high current charging without dedicated battery management logic.
