Alpha and Omega Semiconductor Unveils Powerful Duo of Protection Switches that Support Type-C EPR 3.1 Extended Power Levels
Alpha and Omega Semiconductor Limited (AOS) (Nasdaq: AOSL) a designer, developer, and global supplier of a broad range of discrete power devices, wide bandgap power devices, power management ICs, and modules, today announced two powerful Type-C sink and source protection switches. AOS designed these switches to increase the power delivery capability of USB Type-C ports to 240W, paving the way for Type-C extended power range (EPR) implementations. The AOZ13058DI offers overvoltage/overcurrent protection features suited for 48V Type-C sinking applications, while the AOZ15953DI provides the additional protection features needed for Type-C sourcing applications. These new switches help designers safeguard 48V Type-C EPR capabilities to enhance reliability and functionality in high-performance and gaming laptops, personal computers, monitors, docking, and other higher-power connected portable devices.
