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. Each sensor signal transition is digitally detected, ORied at the.
• Digital Detection of Each Input Transition for Improved Low Speed
Motor Operation
• TTL Compatible Inputs With Hysteresis
• Operation Down to 5.5 V for Direct Powering from MC33035
Reference
• Internal Shunt Regulator Allows Operation from a Non−Regulated
Voltage Source
• Inverter Output for Easy Conversion between 60°/300° and
120°/240° Sensor Phasing Conventions
• Pb−Free Packages are Available
