... The LS7262 is a MOS integrated circuit designed to generate the signals necessary to control a three phase or four phase brushless DC motor. LS7262 is the basic building block of a brushless DC motor controller. The circuit responds to changes at the SENSE inputs originating at the motor position sensors to provide electronic commutation of the motor windings ...

... SG1731 or UC1637 can be interfaced with the LS7262. The logical OR gate made up of the resistor-diode network permits the LS7262 to be enabled when either the forward or reverse input is high. By applying the forward input directly to Pin 19, the motor can only operate in the forward direction when the forward input is high and only in the reverse direction when the reverse input is high ...
