Microchip Technology MCP22350 USB Type-C™ PD 3.1 Port Controllers

Microchip Technology MCP22350 USB Type-C™ Power Delivery (PD) 3.1 Port Controllers are designed to function as a companion PD controller to an external Microchip MCU/SoC. These controllers adhere to USB Type-C™ cable and connector specifications and USB PD 3.1 specifications. The MCP22350, highly-integrated, small form factor PD port controllers offer cable plug orientation and detection for a USB Type-C receptacle. These controllers implement baseband communication with a partner USB Type-C device through the integrated USB PD 3.1 MAC. The MCP22350 controllers include eight configurable general-purpose I/O pins and are available in a 4mm x 4mm 28-QFN package.

The MCP22350 can negotiate alternate modes over USB Type-C connectors using the PD 3.1 protocol. These controllers can be used to support dead battery use cases by selecting between two external 3.3V supplies (VBUS and main) using an integrated power switch.

The MCP22350 controllers integrate analog discrete components, including a power switch, two VCONN FETs with Rp/Rd switching, and current/voltage sensing circuitry for overvoltage/current detection. By integrating the analog discrete components, these PD port controllers provide a low-power solution for consumers (smartphones, tablets, desktop PCs, and notebooks) and industrial applications.
