CASE 626 MC33039, NCV33039 1 1 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. MC33039P
