1 / 9 page _______________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 than a standard 8-pin SO. ________________________Applications Notebook Computers Portable Equipment Hand-Held Instruments Battery Packs ____________________________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 High-Side, n-Channel MOSFET Switch Driver ________________________________________________________________ Maxim Integrated Products 1 1 + 2 3 4 8 7 6 5 BATT SRC GATE GND LBI LBO OFF ON MAX1614 µMAX TOP VIEW PART TEMP RANGE PIN-PACKAGE MAX1614C/D 0°C to +70°C Dice* MAX1614EUA+ -40°C to +85°C 8 µMAX MAX1614EUA/V+ -40°C to +85°C 8 µMAX __________________Pin Configuration MAX1614 OFF LBO GND LBI BATT SRC GATE ON NN LOAD OPTIONAL FOR REVERSE CURRENT PROTECTION R1 R2 __________Typical Operating Circuit 19-1176; Rev 1; 6/11 For pricing, delivery, and ordering information, please contact Maxim Direct at 1-888-629-4642, or visit Maxim’s website at www.maxim-ic.com. ______________Ordering Information * Contact factory for dice specifications. + Denotes a lead(Pb)-free/RoHS-compliant package. /V denotes an automotive qualified part.
