9 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.

9.1 Application Information

The following discussion notes how to implement the device such as distinguish the different fault modes and

transient pulse immunity test.

In some applications, open load, short to battery, and short to GND are required to distinguish from each other.

This requires two steps.

9.2 Typical Application

Figure 45 shows an example of how to design the external circuitry parameters.
