9.3.1 Design 1: Automotive Off-Battery Monitoring

The initial power stage in automotive applications starts with the 12 V battery. Variation of the battery voltage is common between 9 V and 16 V. Furthermore, if cold-cranking and load dump conditions are considered, voltage transients can occur as low as 3 V and as high as 42 V. In this design example, we are highlighting the ability for low power, direct off-battery voltage supervision. Figure 9-2 illustrates an example of how the TPS38-Q1 is monitoring the battery voltage while being powered by it as well. For more information, read this application report on how to achieve low IQ voltage supervision in automotive, wide-VIN applications.
