Overview

The MCP22350T-2I/Q8X is a highly integrated USB Type-C Power Delivery 3.0 port controller designed for small form factor applications. It handles the complexities of USB-PD 3.0 communication, including BMC encoding, SOP detection, and cable orientation, while interfacing with a host controller via SPI. The device features integrated VCONN FETs, dead battery support, and a 3.3V power switch to simplify the bill of materials in charging designs.

Why Choose This Part

This controller minimizes board space by integrating analog components like VCONN FETs and programmable current/voltage sensing. Its dedicated hardware MAC for Power Delivery 3.0 offloads CRC generation, 4B/5B encoding, and packet framing from the main MCU, ensuring robust communication with minimal host overhead.

Applications

USB Type-C Charging Ports
Implementing PD 3.0 negotiation for portable electronics requiring fast charging and power role swapping.
Dead Battery Recovery Systems
Utilizing integrated Rd termination to allow devices with depleted batteries to request power from a source.
Bus-Powered Peripherals
Managing power delivery and data roles for high-performance USB 3.1 peripherals and docking stations.
