The UPD350A-I/Q8X is a highly integrated USB Type-C Power Delivery 3.0 port controller designed for small form factor applications. It features a QFN package measuring 4.0mm x 4.0mm and includes integrated analog discrete components that reduce the overall bill of materials and design footprint. This controller supports USB Power Delivery 3.0 compliance, enabling efficient power management and communication through its I²C/SPI interface. Key functionalities include dual role port (DRP) support, fast role swap (FRS), and USB Type-C alternate mode support for protocols such as DisplayPort. The device also incorporates features like programmable current sense for overcurrent conditions, voltage sense for overvoltage protection, and an integrated 3.3V power switch that provides dead battery support. It is suitable for a variety of applications, including notebook computers, smartphones, tablets, and docking stations. The UPD350A-I/Q8X is available in commercial, industrial, and automotive grade options, with operating temperature ranges from -40°C to +85°C for industrial and automotive versions.
