Note: This is a very simplified example of an application circuit. The function must be verified in the real application.
The circuit above shows a example of using this device in a automotive target application.
D1 is optional for loss of battery or loss of ground if no other circuit on this battery feed can limit the voltage to the
max. rating of the device (-40 V) .
C2 is for EMC and to stabilize the digital driver, recommended value is 47nF.
There are no resistors to the µC needed due to the internal reverse polarity protection.
