MAX1614

19-1176; Rev 0; 12/96 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 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 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 than a standard 8-pin SO. ____________________________Features 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 MAX1614 ________________________Applications Notebook Computers Portable Equipment H...
