Protection circuit

Overvoltage and undervoltage protection

Overtemperature protection (> 75° Celsius on the power board)

Polarity reversal protection: In the event of a polarity reversal, a short-circuit will occur between supply voltage and GND over a power diode; a line protection device (fuse) is therefore necessary in the supply line. The values of the fuse are dependent on the application and must be dimensioned

  • greater than the maximum current consumption of the controller
  • less than the maximum current of the voltage supply.

If the fuse value is very close to the maximum current consumption of the controller, a medium / slow tripping characteristics should be used.
