MC33035DWG

The MC33035DWG is a high performance second generation monolithic brushless DC motor controller in 24 pin SOIC package. It contains all of the active functions required to implement a full featured open loop, three or four phase motor control system. This device consists of a rotor position decoder for proper commutation sequencing, temperature compensated reference capable of supplying sensor power, frequency programmable saw tooth oscillator, three open collector top drivers and three high current totem pole bottom drivers ideally suited for driving power MOSFETs. Also included are protective features consisting of under-voltage lockout, cycle-by-cycle current limiting with a selectable time delayed latched shutdown mode, internal thermal shutdown and an unique fault output that can be interfaced into microprocessor controlled systems. Typical motor control functions include open loop speed, forward or reverse direction, run enable and dynamic braking.
