Rev. 00 BRUSHLESS DC MOTOR CONTROLLER The IL33035 is a high performance second generation monolithic brushless DC motor controller containing all of the active functions required to implement a full featu red open loop, three or four phase motor control system. Thi s device consists of a rotor position decoder for proper com mutation sequencing, temperature compensated reference capab le of supplying sensor power, frequency programmable sawt ooth oscillator, three open collector top drivers, and t hree high current totem pole bottom drivers ideally suited fo r driving power MOSFETs. Also included are protective features consisting of undervoltage lockout, cycle-by-cycle current limiti ng with a selectable time delayed latched shutdown mode, inte rnal thermal shutdown, and a unique fault output that ca n be interfaced into microprocessor controlled systems. Typical motor control functions include open loop speed, forward or reverse direction, run enable, and dynamic braking. The MC33035 is designed to operate with electrical sensor phasings of 60°/300° or 120°/240°, and can also efficiently control brush DC motors
