need to be reverse protected. Also the Resistors in
the digital pins are for reverse polarity protection.
Figure 15 Application Diagram
Note: This is a very simplified example of an application circuit. The function must be verified in the real application.
C1,C2,C3 are recommended to be 4.7nF and all Resistors can be 1kOhm.
