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, prev...
