Signal-Line Protector

General Description
The MAX4505 is a single signal-line protector featuring a
fault-protected input and Rail-to-Rail
signal handling
capability. The input is protected from overvoltage faults
up to ±36V with power on or ±40V with power off. During
a fault condition, the input terminal becomes an open cir-
cuit and only nanoamperes of leakage current flow from
the source, while the switch output (AOUT) furnishes typ-
ically 19mA from the appropriate polarity supply to the
load. This ensures an unambiguous rail-to-rail output
when a fault begins and ends.
The MAX4505 protects both unipolar and bipolar analog
signals using either unipolar (+9V to +36V) or bipolar
(±8V to ±18V) power supplies. The device has no logic
control inputs; the protector is always on when the sup-
plies are on. On-resistance is 100
max, and on-leakage
is less than 0.5nA at TA = +25°C. The MAX4505 is avail-
able in 5-pin SOT23 and 8-pin MAX packages.
