Device for driving switching elements

A device for driving switching elements is provided with a potential detector which provides drive circuit with signals in response to differences among potentials at junctions to of first and third resistors , third resistor and first control MOS-FET , second and fourth resistors and fourth resistor and second control MOS-FET so that drive circuit supplies drive signals to a gate terminal of a first MOS-FET based on potentials in first and second series circuits and . When appropriate resistance values are selected for first to fourth resistors to , potential detector precisely detects the potential at each junction to to produce detection signals and prevent malfunction of drive circuit even upon occurrence of abnormal signals or noises resulted from abrupt potential rise.
