Alpha and Omega Semiconductor Limited (AOS) announced the release of the AOZ1334, a single-channel EZPower™ Smart Load Switch. The device features an ultra-low on-resistance of 3.9 mΩs, and delivers up to 10 A of continuous current in a thermally enhanced 3 mm x 3 mm DFN package. The AOZ1334 offers high efficiency in a compact size, and is an ideal solution for a variety of space-constrained applications such as tablets, notebook computers, set-top-boxes, solid-state drives, networking equipment, LCD TVs, and other consumer electronics applications.
The AOZ1334 includes an n-channel MOSFET that can provide 10 A of current with a 3.2 V to 5.5 V bias supply, and operates down to 0.8 V. The MOSFET turn-on time is controlled by a low voltage control signal through the ON pin. Additionally, an internal 220Omega load discharge resistor is integrated to allow quick discharging of capacitive output loads.
The AOZ1334 is immediately available in production quantities with a lead-time of 12 weeks. The unit price of 1,000 pieces is $0.66.
