UPD301A-I/KYX

Controllers Overview

The UPD301A is a stand-alone USB Type-C Power Delivery 3.0 controller designed for source-only applications. It integrates an ARM Cortex-M0+ core with preprogrammed PD firmware, supporting power profiles of 15W, 27W, 45W, and 60W via configurable straps. The device features a built-in MAC for baseband communication, cable orientation detection, and VCONN control. It operates within a commercial temperature range of 0°C to +70°C or an industrial/automotive grade 3 range of -40°C to +85°C. The component is housed in a 40-VQFN (6.0mm x 6.0mm) package.

Controllers Feature Summary

• Preprogrammed USB Power Delivery 3.0 firmware stack eliminates custom development requirements.
• Integrated analog discrete components including VCONN FETs and current/voltage sense circuitry reduce bill of materials.
• Supports optional dual-port configurations through SPI connection with the external UPD350 controller.
• Configurable pin straps allow selection of specific power delivery profiles and I2C addresses.

Controllers Applications

• Point-of-Sale Terminals
• Charging Lockers
• IoT Products and Sensors
• Smart Speakers and Monitors
• Automotive Rear Seat Charging Ports

Controllers Procurement Notes

Verify the specific suffix indicates the required temperature grade. The standard version supports commercial temperatures, while automotive-grade parts require AEC-Q100 qualification confirmation. Ensure the ordering code matches the intended operating environment and that the datasheet revision corresponds to the silicon version being procured.

Controllers Selection Notes

Select this component for standalone source-only implementations requiring minimal host MCU intervention. Use the configuration straps to define fixed power delivery objects without software overhead. Consider the UPD350 add-on if dynamic power allocation across two ports is necessary. Verify voltage levels match the target DC-DC converter interface.

Controllers Part Context

This part belongs to Microchip's USB Type-C Power Delivery controller family. It serves as a dedicated port controller for implementing compliant USB-C charging solutions. The device simplifies design by integrating the protocol stack and essential analog front-end functions into a single small form-factor package.
