This device requires minimal protection circuitry
during operation with a low-voltage regulated line.
The on-chip voltage regulator provides immunity
to power supply variations between 3.3 and 18 V.
Because the device has open-collector outputs, pull-
up resistors must be included.
If protection against coupled and injected noise is
required, then a simple low-pass
fi
lter on the supply
(RC) and a
fi
ltering capacitor on each of the outputs
may also be needed, as shown in the unregulated
supply diagram.
For applications in which the device receives its
power from unregulated sources, such as a car bat-
tery, full protection is generally required to protect the
device against supply-side transients. Speci
fi
cations
for such transients vary for each application, so the
design of the protection circuit should be optimized
for each application.
For example, the circuit shown in the unregulated
supply diagram includes a Zener diode that offers
high voltage load-dump protection and noise
fi
ltering
by means of a series resistor and capacitor. In addi-
tion, it includes a series diode that protects against
high-voltage reverse battery conditions.
