The from Products is a high side, N-channel MOSFET switch driver in 8 pin µMAX package. It drives high side, N-channel power MOSFETs to provide battery power switching functions in portable equipment. The N-channel power MOSFETs typically has one-third the on-resistance of P-channel MOSFETs of similar 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 system microprocessor or disconnect the battery from load, preventing deep discharge and battery damage. An internal latch allows for pushbutton on/off control with very low current consumption. Typical applications include notebook computer, hand held instruments mad battery packs.
