MCP22301

The MCP22301 is a stand-alone, small form factor USB Type-C® Power Delivery (PD) Port Controller compliant with the USB Type-C® Power Delivery 3.1 Specification. The MCP22301 provides stand-alone operation for a wide range of PD applications, enabling cable plug orientation and detection for a USB Type-C® receptacle, and implementing baseband communication with the connecting USB Type-C® device via the integrated USB Power Delivery 3.1 MAC.

The MCP22301 is an integrated PD solution with the functionality of a SAMD20 (32-bit ARM Cortex-M0+) microcontroller and a MCP22350 PD MAC/PHY. Optionally, a second, third, or fourth PD port is supported via SPI connection to additional external Microchip MCP22350 devices. The embedded 32-bit ARM Cortex-M0+ executes the Microchip USB Power Delivery Stack (PDS). The MCP22301 devices are shipped blank and require programming with compiled application specific code before operation. Programming is supported by Microchip's industry standard MPLAB X IDE programming environment.

The PDS is a light weight USB PD stack that is designed to integrate any suitable powerful MCU with Microchip's MCP22301 standalone Type-C® PD controller and MCP22350 Type-C® PD controller to realize multi-port custom PD solutions. PDS provides a range of configuration options for your custom PD design and is portable to many MCUs.

The PDS firmware stack allows for a wide range of USB Power Delivery applications, including but not limited to: USB PD v3.1 fixed and Programmable Power Supply (PPS) source only applications, Multi-Port PD Source, VCONN sourcing and Fault Handling, and I2C and GPIO Mode DC/DC control. The PDS firmware stack is a continuously deployed open source stack. Not all features that are able to be supported by the MCP22301 device are necessarily supported by PDS. The supported features may be expanded over time. Additional feature development or status of basic feature development may be requested through Microchip support channels.

By integrating the PD firmware and many of the analog discrete components required for USB Type-C® PD applications, the MCP22301 provides a flexible, stand-alone, PD solution for designers who wish to integrate the PD operation with a system controller, implement a custom power supply circuit, support unique PDOs or charging algorithms, or simply control their own PD code.
