DESCRIPTION
The APE8991A is a small, ultra-low R_ON load switch
with controlled turn on. It contains one N-channel
MOSFET that can operate over an input voltage
range of 0.8V to 5.5V and support maximum
continuous current up to 4A. The switch is controlled
by an on/off input (EN), which is capable of
interfacing directly with low-voltage control signals.
Additional features include a 330Ω on-chip load
resistor is added for output quick discharge when
switch is turned off. A well protection is equipped
when the device enters hard short circuit and
thermal shutdown.
The APE8991A is available in 8-pin DFN 3x3-8L
package with smallest components.
