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,C1 are used for blocking negative disturbances from Battery supply.
D2 is optional for loss of battery if no other circuit on this battery feed can limit the voltage to the negative max.
rating of the device (-16 V) .
D3 is limiting the battery voltage below the maximum rated positive voltage of the
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.
