Signal-Line Overvoltage Protector
for Low-Voltage Devices
General Description
The MAX9940 signal-line overvoltage protector for low-
voltage digital communication ports provides protection
against high-voltage faults and ESD strikes. The
MAX9940 is especially useful for sensitive communica-
tion protocols such as Maxim 1-Wire ? that cannot
afford standard means of fault protection, such as large
series resistors or large line capacitances.
The MAX9940 operates from a single supply voltage of
+2.2V to +5.5V and consumes only 13μA of quiescent
supply current. The EXT port is protected up to 28V.
The device features a reaction time of 60ns for fast
action during fault conditions and operates over the
-40°C to +125°C automotive temperature range.
