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 FEATURES • 10 to 30 V Operation • Undervoltage Lockout • 6.25V 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 H-Bridge 2011, February, Rev. 01 IL33035 Absolute maximum ratings Parameter Power Supply Voltage Digital Inputs (Pins 3, 4, 5, 6, 22, 23) Oscillator Input Current (Source or Sink) Error Amp Input Voltage Range (Pins 11, 12, Note 1) Error Amp Output Current (Source or Sink, Note 2) Current Sense Input Voltage Range (Pins 9, 15) Fault Output Voltage Fault Output Sink Current Top Drive Voltage (Pins 1, 2, 24) Top Drive Sink Current (Pins 1, 2, 24) Bottom Drive Supply Voltage (Pin 18) Bottom Drive Output Current (Source or Sink, Pins 19, 20. 21) Power Dissipation and Thermal Characteristics DIP package Maximum Power Dissipation TA = 85oC Thermal Resistance.
