High-Side, n-Channel MOSFET

Switch Driver

MAX614

_______________General Description

____________________________Features

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.

o Internal On/Off Latch

o High-Side, n-Channel Power MOSFET Drive

o 25µA (max) Quiescent Current

o 6µA (max) Off Current

o Requires No External Components

o 1.5%-Accurate Low-Battery Detector

o Space-Saving µMAX Package

o 5V to 26V Input Voltage Range

o Drives Single or Back-to-Back MOSFETs

o Controlled Turn-On for Low Inrush Current

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

______________Ordering Information
