HIGH SIDE POWER SWITCHES
DESCRIPTION
The UTC US94060 are high-side load switches incorporating a low
on-resistance P-channel MOSFET which provides customers over 2A
continuous current.

The UTC US94060 is characterized by a fast turn on function. The
UTC US94060 keeps in a floating state when an active pull-down
signals is on the enable input until a high level signal applies on the EN
pin. Built-in level shift circuitry allows low voltage logic signals to switch
to higher supply voltages, on the contrary, high level logic signals can
control low level voltages.

The UTC US94060’s operating voltage varies from 1.8V ~ 5.5V
which makes these devices suitable for 1-cell Lithium ion and 2- to
3-cell NiMH/NiCad/Alkaline powered systems as well as all 5V
applications. The 2µA low operating current and low shutdown
current(less than1µA) make the battery life longer.
SOT-26
The UTC US94060 is generally suitable for applications, such as
load switch in portable devices: cellular phones, PDAs, MP3 players,
digital Cameras, portable instrumentation, battery switch-over circuits
and level translators.
FEATURES
* Operating voltage range:1.8V ~ 5.5V
* Providing 2A continuous operating current
* P-channel MOSFET’s RON : 175mΩ typical
* Built-in level shift for control logic
* Quiescent current is as low as 2µA
* Micro-power shutdown less than 1µA
