Detailed Description
The MAX14634 is a bidirectional switch with ultra-low 7mI
(typ) on-resistance and reverse-current blocking capabil-
ity. The device has low quiescent current and operates
from a +2.3V to +5.5V input voltage range, making this
device ideal as a battery-disconnect switch for high-
capacity battery applications. The slew-rate controlled
switch is also ideal for a large load capacitor as well as
high-current load switching applications.
Reverse-Current Blocking
The bidirectional FET switch prevents current flowing
from either power input to the other when the switch is
disabled.
EN Input
The switch position is controlled by an EN active-low
logic input. The switch is on when EN is logic-low and
off when EN is logic-high. EN is internally pulled down to
ground by R_PD.
