Pin Configuration
The APL3580 series are 33mΩ 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.
