The APE8937 is a small, ultr
A
ra-low R
ON
lo switch
oad
with controlled tu on. It co
c
urn
ontains one N-channel
MOSFET that ca operate o
an
over an inp voltage
put
range of 0.8V to 5.5V an support maximum
e
nd
contin
nuous curren up to 6A. T switch is controlled
nt
The
s
by an on/off in
a
nput (EN), which is capable of
c
interfa
acing directly with low-vo
y
oltage control signals.
Additional feature include a 300Ω on-chip load
es
resist for outpu quick disc
tor
ut
charge when switch is
n
turned off, in orde to avoid inrush curren the rise
d

nt,
time is adjustable by an exte

c
on the CT pin.
