MC33035P DIP IC

The MC33035 is a high performance second generation monolithic
brushless DC motor controller containing 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 sawtooth 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 undervoltage
lockout, cycle?by?cycle current limiting with a selectable time
delayed latched shutdown mode, internal thermal shutdown, and a
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. The MC33035 is
designed to operate with electrical sensor phasings of 60?/300? or
120?/240?, and can also efficiently control brush DC motors.
