Mechanical Switch Monitor
The MAX1608/MAX1609’s ability to perform IO_ logic-
state readback makes them suitable for checking sys-
tem status. They can be used as an “open-lid indicator,”
sensing a change in the IO_ and sending an interrupt
to the master to indicate a change in status (Figure 9).
The same can be done to detect a chassis intrusion, a
reset switch, or a card insertion.
Simple High-Voltage Switch
For applications requiring a higher voltage, use a sim-
ple resistive divider to protect the gate from breakdown
yet allow the MOSFETs to handle higher voltage appli-
cations (Figure 10).
