Application Examples
P-Channel/N-Channel High-Side Load
Switch with Controlled Turn-On
In load-switching applications, when a controlled volt-
age ramp or inrush current limiting is required, add a
series resistor to slow the switch turn-on and turn-off
times. The external MOSFET gate has a typical capaci-
tance of 150pF to 2000pF, but an optional external
capacitance can be added to further slow the switching
time (Figure 6). If a slow turn-on time is required, simply
use an N-channel MOSFET with a high-value pull-up
resistor and no series resistor. Similarly, if a fast turn-on
and a slow turn-off are desired, use a P-channel MOS-
FET with a high-value pull-up resistor and no series
resistor.
Battery Switch with
Back-to-Back MOSFETs
Many battery-operated applications use back-to-back
MOSFETs to prevent reverse currents from the load to
the supply (Figure 7). This protects the battery from
potential damage and isolates the load from the power
source.
LED Driver
A MAX1608/MAX1609 can be used as programmable
LED drivers (Figure 8). With their low quiescent current,
these devices are ideal for use as indicator light drivers
on the front panel of a notebook computer.
