MC33039, CLOSED LOOP BRUSHLESS MOTOR ADAPTER
The MC33039 provides an economical method of implementing closed *loop speed control of brushless DC motors by eliminating the need for a magnetic or optical tachometer.
Shown in the timing diagram of Figure 1, the three inputs (Pins 1, 2, 3) monitor the brushless motor rotor position sensors
Order this document by MC33039/D MC33039 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.
