MAX1614
High-Side, n-Channel MOSFET
Switch Driver
_______________General Description
The MAX1614 drives high-side, n-channel power MOSFETs
to provide battery power-switching functions in portable
equipment. The n-channel power MOSFETs typically have
one-third the on-resistance of p-channel MOSFETs of simi-
lar size and cost. An internal micropower regulator and
charge pump generate the high-side drive output voltage,
while requiring no external components.
The MAX1614 also features a 1.5%-accurate low-battery
comparator that can be used to indicate a low-battery
condition, provide an early power-fail warning to the sys-
tem microprocessor, or disconnect the battery from the
load, preventing deep discharge and battery damage. An
internal latch allows for pushbutton on/off control with very
low current consumption. Off-mode current consumption
is only 6μA while normal operation requires less than
25μA. The MAX1614 is available in the space-saving
μMAX ? package that occupies about 60% less space
