MC33035P onsemi MOTOR DRIVER

The MC33035 is a extreme effectivity second period monolithic brushless DC motor controller containing your complete energetic options required to implement a full featured open loop, three or 4 part motor administration system. This machine consists of a rotor place decoder for proper commutation sequencing, temperature compensated reference capable of supplying sensor vitality, frequency programmable sawtooth oscillator, three open collector prime drivers, and three extreme current totem pole bottom drivers ideally suited to driving vitality MOSFETs. Moreover included are defending choices consisting of undervoltage lockout, cycle−by−cycle current limiting with a selectable time delayed latched shutdown mode, interior thermal shutdown, and a singular fault output that could be interfaced into microprocessor managed applications. Typical motor administration options embody open loop tempo, forward or reverse path, run enable, and dynamic braking. The MC33035 is designed to operate with electrical sensor phasings of 60°/300° or 120°/240°, and may successfully administration brush DC motors.
