8 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
8.1 Application Information
The following discussion notes how to implement the device to distinguish the different fault modes and
implement a ? transient-pulse immunity test.
In some applications, open load, short to battery, and short to GND must be distinguished from each other. This
requires two steps.
8.2 Typical Application
Figure 45 shows an example of how to design the external circuitry parameters.
