The APL3580 series are 33m

Ω high-side load switches

designed to be operated from 1.5V to 5.5V. The load

switch that supports 1.5V logic level control and shut-

down features can deliver load current up to 3A.

The APL3580 incorporates a soft-start control circuitry to

limit inrush current during powering-up. When disabled,

an internal discharge circuit automatically discharges a

capacitive load. The enable input pin is actively pulled

down to keep the device in off state until the enable pin is

pulled above 1.2V. The level shift circuitry allows low volt-

age logic signals to switch higher supply voltage. The EN

input voltage can be as high as 5.5V and is not limited by

the input voltage.

With the virtues of low quiescent current and low shut

down current, the APL3580 series are ideal for battery

powered systems to maximum battery life, as well as

non-battery powered applications. They are available in

tiny 1.2mmx1.2mm WLCSP-4 packages.
