摘要： An integrated circuit includes a first inner circuit including at least one first semiconductor device, a second inner circuit including at least one second semiconductor device, and a fusing circuit connected between the first inner circuit and the second inner circuit to perform a fusing operation which electrically disconnects the first inner circuit from the second inner circuit through a fusing voltage. The fusing circuit bypasses a spark current occurring during the fusing operation to a ground power source so as not to flow the spark current into the first inner circuit and the second inner circuit.

摘要： A circuit for driving a sensorless BLDC motor is disclosed which checks whether or not the motor is rotating and then terminates the start up interval (or forced drive interval) in order to obtain efficient motor drive. The present invention is comprised of a comparator which receives a phase voltage through a first input terminal and receives a neutral point voltage through a second input terminal, and a flip-flop unit which is comprised of a plurality of flip-flop devices. Each flip-flop device is a means for receiving an output of the comparator through a clock signal input terminal, and a reset signal through a reset signal input terminal. The sensorless BLDC motor operates in a running mode when data provided to the input terminal of the first flip-flop means is output from the output terminal of the last flip-flop.
