AOZ1375 load switch. Image credit: Alpha & Omega Semiconductor Alpha and Omega Semiconductor Limited has introduced the AOZ1375, AOS's first Type-C Power Delivery full-compliant power protection switch. The AOZ1375 is a bidirectional current-limited load switch with reverse current blocking capability intended for applications that require circuit protections and soft-start function. This device offers RDS(ON) of 17.8 mΩ in a thermally enhanced 3 x 3mm DFN package, suiting it for notebooks, ultrabooks, desktops, monitors, dockings/dongles and Thunderbolt/USB Type-C PD applications.
The device operates from voltages between 3.4 V and 23 V and features two power switch terminals, VINT and VBUS, which are rated at 28 V absolute maximum. When used as a source switch, the internal current limiting circuit protects the supply from large load current. The back-to-back switch configuration blocks any leakage between VINT and VBUS pins when the device is disabled.
The AOZ1375 is fully programmable with comprehensive protections, including soft start; short-circuit protection, thermal protection, over-current and over-voltage protection. Multiple operating voltages (5 V/9 V/15 V/20 V) with programmable over-voltage threshold make it fully compliant with the USB PD 3.1 power profile.
The AOZ1375 is immediately available in production quantities with a lead-time of 12 weeks. The unit price of 1,000 pieces is $3.30.
