MC33035
Brushless DC
Motor Controller
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.
• 10 to 30 V Operation
• Undervoltage Lockout
• 6.25 V Reference Capable of Supplying Sensor Power
• Fully Accessible Error Amplifier for Closed Loop Servo Applications
• High Current Drivers Can Control External 3–Phase MOSFET Bridge
• Cycle–By–Cycle Current Limiting
• Pinned–Out Current Sense Reference
• Internal Thermal Shutdown
• Selectable 60°/300° or 120°/240° Sensor Phasings
• Can Efficiently Control Brush DC Motors with External MOSFET
