UPD301AT/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 embedded 32-bit ARM Cortex-M0+ processor running preprogrammed PD firmware, eliminating the need for custom code development. The device supports standard power profiles of 15W, 27W, 45W, and 60W via configurable pin straps. It features an integrated USB PD MAC handling baseband communication, CRC checking, and packet framing. Analog components such as VCONN FETs and current/voltage sense circuits are included to reduce bill of materials. Configuration is achieved through external resistors on pins like PDP_SEL0 and I2C_ADDR_SEL.

Controllers Feature Summary

• Preprogrammed USB Power Delivery 3.0 firmware stack eliminates custom development requirements.
• Integrated analog discrete components including VCONN FETs and overcurrent/overvoltage detection circuitry.
• Stand-alone operation with configuration defined by external pin straps for power profiles and addresses.
• Supports optional dual-port expansion via SPI connection to an external UPD350 controller.

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 KYX suffix denotes the industrial and automotive grade variant operating from -40°C to +85°C. Confirm package availability in the 40-VQFN format. Ensure ordering documentation matches the exact part number to guarantee correct firmware and environmental ratings.

Controllers Selection Notes

Select this component for turnkey USB-C source implementations requiring minimal host MCU intervention. Use the KYX suffix when deployment environments exceed commercial temperature limits or require AEC-Q100 Grade 3 compliance. Verify that the fixed voltage and current configurations provided by the pin straps align with the target application's power delivery requirements.
