Switching transistor driver circuit controlling power supply to the load

Of a pair of switching transistors connected in series between a high voltage power source and the ground, when the switching transistor on the high potential side is controlled by an RS flip-flop in response to an input signal, in order to prevent a malfunction caused by the influence of dv/dt transient phenomena of an output terminal for driving a load, a latch circuit is reset using an input signal from a low side input terminal LIN in a period during which the voltage of the output terminal for driving the load abruptly decreases.
