Alpha and Omega Semiconductor Introduces First USB Type-C Load Switch
April 06 2017 - 5:57PM
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 AOZ1375, AOS's
first Type-C Power Delivery full-compliant power protection
switch. 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 a best-in-class RDS(ON) (17.8mohm) 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 device operates from voltages between 3.4V
and 23V, and features two power switch terminals, VINT and VBUS
which are rated at 28V Absolute Maximum. This is a perfect
protection load switch solution for battery charging using USB PD
protocol. 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 (5V/9V/15V/20V) with
programmable over-voltage threshold make it fully compliant with
USB PD 3.1 power profile.
“As the USB Type-C PD adoption continues to rise in
popularity in notebooks, ultrabooks, desktops, and wire connected
devices, designers and users are looking for higher power, higher
speed and higher performance solutions to support this market
trend,” said Kenny Hu, Power IC Marketing Manager at AOS. “The
combination of low on-resistance, robust ESD and full programmable
protections allow AOZ1375 to offer industry-leading performance,
making it the ideal smart load switch for a variety of USB Type-C
PD applications.”
