TECHNICAL DATA
BRUSHLESS DC MOTOR CONTROLLER
IL33035
The IL33035 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

* Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device.
These are stress ratings only and functional operation of the device at these or any other conditions beyond those
indicated under “recommended operating conditions” is not implied.
Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
