Alpha and Omega Semiconductor Enhances the EZPower™ Smart Load Switch
Portfolio with Rapid Turn-Off Fault Protection and Current Monitoring
SUNNYVALE, Calif., Aug. 7, 2014 – 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 the AOZ1363, a
high current smart load switch with rapid turn-off fault protection and current monitoring. The device has an operating input
voltage range from 5V to 16V and is capable of supplying up to 6A of continuous current. A low on-resistance of 23mΩ in a
thermally enhanced 3mm x 3mm DFN package makes the AOZ1363 optimal for space-constrained applications that require
circuit protection such as the latest notebook PCs, hot swap supplies and micro servers.
The AOZ1363 integrates several smart functions to safely and effectively manage, and monitor loads. The device features an
internal current limiting circuit, which protects the system from sourcing excessive load currents, in conjunction with a
thermal protection function that limits excessive power dissipation. Externally programmable soft-start circuitry controls
inrush current from highly capacitive loads during hot-plug events. The device can communicate load information in real
time through the current monitoring pin (ISEN) with an accuracy window of 10% at a specified load current of 3A. The
AOZ1363 can detect over-current fault conditions and execute a rapid power-down within a delay time of 100ns maximum.
It also features an input overvoltage protection which allows the device to power-down when the power input voltage
exceeds 19V. Efficiency is not sacrificed as the AOZ1363 features a low quiescent current of 400μA that can be further
reduced to less than 10μA in shutdown mode.
“The combination of smart functions, wider input voltage range, low on-resistance, and a thermally enhanced compact DFN
package enables the AOZ1363 to achieve exceptional performance, making it a distinctive and ideal load switch for a variety
of space-constrained applications” said Daniel Chang, Vice President of the Power IC Product Line at AOS.
Pricing and Availability
The AOZ1363 is immediately available in production quantities with a lead-time of 12 weeks. The unit price of 1,000 pieces
is $3.75.
