PURPOSE:To provide a pre-drive circuit, in which the driving system, etc., of a motor can be changed by programming and which has high general-purpose properties and is used for the brushless motor. CONSTITUTION:A signal for driving a brushless motor is formed on the basis of a signal transmitted over an input terminal 2 in the input terminal section 2 consisting of three input terminals, all terminals or partial terminals of which are supplied with a signal regarding the positional information of the brushless motor, and one input terminal supplied with a comparison signal to the signal transmitted over the input terminals and an output terminal section 3 composed of six output terminals, from all terminals or partial terminals of which the signal for driving the brushless motor is output. A programmable logic generating means 13 outputting a programmable logic to the output terminal 3 is provided. |
