Alpha and Omega Semiconductor Introduces Protected Smart Load Switch for USB Type-C Applications

Industry-leading performance, up to 28V over-voltage protection, current limiting and true reverse blocking

SUNNYVALE, Calif., March 15, 2018 (GLOBE NEWSWIRE) -- Alpha and Omega Semiconductor Limited (AOS) (Nasdaq:AOSL), a designer, developer and global supplier of a broad range of power semiconductors and power ICs, today introduced a new Type-C Power Delivery compliant load switch with up to 28V over-voltage protection.  AOZ1353 is a current-limited load switch with reverse current blocking capability intended for applications where internal circuitry requires protection from exposure to high voltages. This new device offers low RDS(ON) (40mohm) in a thermally enhanced 3x3mm DFN package, making it an ideal solution for the latest notebooks, ultrabooks, desktops, monitors, dockings/dongles, and Thunderbolt/USB Type-C PD applications.

The new AOZ1353 operates from voltages between 3.4V and 5.5V from VIN and VOUT is rated at 28V Absolute Maximum. The internal current limiting circuit protects the supply from large load currents. The back-to-back switch configuration blocks any leakage between VIN and VOUT pins when the device is disabled or when the device is enabled, but VOUT is greater than VIN. The AOZ1353 is fully programmable with comprehensive protection features including soft start, short-circuit protection, thermal protection, over-current and over-voltage protection.

“As the USB Type-C PD adoption with its higher power and greater flexibility continues to rise in popularity in notebooks, ultrabooks, desktops, and other connected devices, designers are looking for solutions that offer the necessary protections for the system and its battery against exposure to higher voltages and currents,” said Mehdy Khotan, Power IC Marketing Director at AOS. “The combination of  low quiescent current, low RDS(ON), robust ESD and protection features allow AOZ1353 to offer industry-leading performance, making it the ideal power source switch for USB Type-C PD applications.”
