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-drain outputs, pull-up
resistors must be included.
If protection against coupled and injected noise is
required, then a simple low-pass lter on the supply
(RC) and a 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 battery, full
protection is generally required to protect the device
against supply-side transients. Specications 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 ltering by
means of a series resistor and capacitor. In addition, it
includes a series diode that protects against high-volt-
age reverse battery conditions.
