MAX1614EUA+T

The MAX1614EUA+T 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.

• Integration provides a simple to use solution
• Internal on/off latch facilitates pushbutton control
• 1.5% accurate low battery detector protects battery and data stored in memory
• Controlled turn-on for low inrush current
• Off mode current consumption is only 6μA while normal operation requires less than 25μA
• Supports typical requirements of portable, battery powered designs
• Drives single or back to back MOSFETs, low power consumption extends battery life
• 5V to 26V batt operating range, 8V GATE drive voltage at VBATT = 15V, IGATE = 0A (TA = -40 to +85°C)
• 8μA batt shutdown current, 40μA quiescent current at TA = -40°C to +85°C
• Operating temperature range from -40°C to +85°C
