Closed Loop Brushless

Motor Adapter

The MC33039 is a high performance closed−loop speed control

adapter specifically designed for use in brushless DC motor control

systems. Implementation will allow precise speed regulation without

the need for a magnetic or optical tachometer. This device contains

three input buffers each with hysteresis for noise immunity, three

digital edge detectors, a programmable monostable, and an internal

shunt regulator. Also included is an inverter output for use in systems

that require conversion of sensor phasing. Although this device is

primarily intended for use with the MC33035 brushless motor

controller, it can be used cost effectively in many other closed−loop

speed control applications.
