MCP22350-2I/Q8X

Controllers Overview

The MCP22350-2I/Q8X is a highly integrated, small form factor USB Type-C Power Delivery 3.1 port controller designed to adhere to the USB Type-C Cable and Connector Specification and USB PD 3.1 Specification. It provides cable plug orientation and detection for a USB Type-C receptacle and implements baseband communication with partner devices via an integrated MAC. Designed as a companion controller for external Microchip MCUs or SoCs, it utilizes an SPI interface for configuration and control. The device integrates analog discrete components including VCONN FETs, power switches, and current/voltage sense circuitry. It operates within a voltage range of 4.75 V to 5.25 V, consumes 15 mA during operation, and functions across an industrial temperature range from -40°C to +85°C.

Controllers Feature Summary

• Integrated USB Power Delivery 3.1 MAC supporting baseband communication and protocol compliance
• Hardware dead battery support enabling connection detection without external processor intervention
• Integrated analog components including VCONN FETs with Rp/Rd switching and programmable overcurrent/overvoltage detection
• Dual Role Port (DRP) and Fast Role Swap (FRS) support with DRP offload mode capabilities

Controllers Applications

• Notebook Computers
• All-in-One/Desktop PCs
• Smartphones
• Tablets
• Multi-Port Chargers

Controllers Procurement Notes

Verify the specific suffix 'Q8X' against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Ensure the ordering code matches the required industrial temperature grade and that the component is sourced from authorized distributors to guarantee authenticity and traceability.

Controllers Selection Notes

Select the MCP22350-2 variant specifically when hardware-based dead battery support is required for system wakeup and connection detection. Confirm compatibility with the host Microchip MCU or SoC via the SPI interface. Verify that the 28-QFN package dimensions fit the design footprint constraints.

Controllers Part Context

This component belongs to the MCP22350 family of USB Type-C PD controllers. The '-2' designation indicates the inclusion of hardware dead battery support features not present in the '-1' variant. It serves as a dedicated companion controller to offload PD management tasks from the main system processor.
