Maxim Integrated
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 similar size and cost. An internal micropower regulator and charge pump generate the high-side drive output voltage, while requiring no external components.
