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.

Features

•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

OPERATING DESCRIPTION

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 Latch iSeti Input, and causes CT to

discharge. A corresponding output pulse is generated at fout

(Pin 5) of a defined amplitude, and programmable width

determined by the values selected for RT and CT (Pin 6). The

average voltage of the output pulse train increases with

motor speed. When fed through a low pass filter or

integrator, a DC voltage proportional to speed is generated.

Figure 2 shows the proper connections for a typical closed

loop application using the MC33035 brushless motor

controller. Constant speed operation down to 100 RPM is

possible with economical three phase four pole motors.

The φA inverter output (Pin 4) is used in systems where the

controller and motor sensor phasing conventions are not

compatible. A method of converting from either convention

to the other is shown in Figure 3. For a more detailed

explanation of this subject, refer to the text above Figure 39

on the MC33035 data sheet.

The output pulse amplitude VOH is constant with

temperature and controlled by the supply voltage on VCC

(Pin 8). Operation down to 5.5 V is guaranteed over

temperature. For systems without a regulated power supply,

an internal 8.25 V shunt regulator is provided.
