Brushless DC Motor Controller MC33035P
Brushless DC Motor Controller MC33035P
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 under-voltage 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 phasing of 60°/300° or 120°/240°, and can
also efficiently control brush DC motors.
