MAX1614 High-Side, n-Channel MOSFET Switch Driver General Description Benefits and Features The MAX1614 drives high-side, n-channel power Integration Provides a Simple-to-Use Solution MOSFETs to provide battery power-switching functions Requires No External Components in portable equipment. The n-channel power MOSFETs Internal On/Off Latch Facilitates Pushbutton typically have one-third the on-resistance of p-channel Control MOSFETs of similar size and cost. An internal micropower 1.5% Accurate Low-Battery Detector Protects regulator and charge pump generate the high-side drive Battery and Data Stored in Memory output voltage, while requiring no external components. Controlled Turn-On for Low Inrush Current The MAX1614 also features a 1.5%-accurate low-battery Low Power Consumption Extends Battery Life comparator that can be used to indicate a low-battery 25A (max) Quiescent Current condition, provide an early power-fail warning to the 6A (max) Shutdown Current system microprocessor, or disconnect the battery from the MAX Package is 60% Smaller Than Typical 8-Pin load, preventing deep discharge and battery damage. An SO Solution internal latch allows for pushbutton on/off control with very Supports Typical Requirements of Portable, Battery- low current consumption. Off-mode current consumption Powered Designs is only 6A while normal operation requires less than 25A. The MAX1614 is available in the space-saving 5V to 26V Input Voltage Range MAX package that occupies about 60% less space Drives Single or Back-to-Back MOSFETs than a standard 8-pin SO.
