Detailed Description
Overview of Traditional
Fault-Protected Switches
The MAX4510/MAX4520 are fault-protected CMOS
analog switches with unusual operation and construc-
tion. Traditional fault-protected switches are construct-
ed by three series FETs. This produces good off
characteristics, but fairly high on-resistance when the
signals are within about 3V of each supply rail. As the
voltage on one side of the switch approaches within
about 3V of either supply rail (a fault condition), the
switch impedance becomes higher, limiting the output
signal range (on the protected side of the switch) to
approximately 3V less than the appropriate polarity
supply voltage.
During a fault condition, the output current that flows
from the protected side of the switch into its load comes
from the fault source on the other side of the switch. If
the switch is open or the load is extremely high imped-
ance, the input current will be very low. If the switch is
on and the load is low impedance, enough current will
flow from the source to maintain the load voltage at 3V
less than the supply.
