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. 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 6碌A(chǔ) while normal operation requires less than
25碌A(chǔ). The MAX1614 is available in the space-saving
碌MAX package that occupies about 60% less space than
a standard 8-pin SO.
