HIGH SIDE POWER SWITCHES

DESCRIPTION

The UTC US94061 are high-side load switches incorporating a low

on-resistance P-channel MOSFET which provides customers over 2A

continuous current.

The UTC US94061 is characterized by a fast turn on function. The

UTC US94061 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 US94061’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.

The UTC US94061 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.
