Abstract
In a circuit (3) a MOSFET (14) is used for protecting a load (18) against wrong polarity of a power source (11) for the circuit (3). A driver (15) for the MOSFET (14) is configured to generate a pre-defined voltage drop between source (141) and drain (142) of the MOSFET (14) at correct polarity of power source (11). If wrong polarity of power source (11) is detected, driver (15) sets MOSFET (14) into a state of high resistance between source (141) and drain (142). The pre-defined voltage drop at correct polarity is associated with a resistance between source (141) and drain (142) which makes detection of wrong polarity more reliable.
