Good morning,
I just made a circuit with 71550. Input voltage of 18V. Feeds a comparator that activates or deactivates a POWER MOSFET according to the battery voltage (18V). The MOSFET driving a ON/OFF DC motor.
It happens very often that during power circuit controller 71550 burns. I've already replaced four pieces.
Does anyone know why you can burn quickly so every?
thanks
