9 Application and Implementation
备注
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, as well as validating and testing their design
implementation to confirm system functionality.
9.1 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
action requires two steps.
9.2 Typical Application
图9-1 shows an example of how to design the external circuitry parameters.
