MC33039, NCV33039
Closed Loop Brushless
Motor Adapter
The MC33039 is a high performance closedloop 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 closedloop
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 NonRegulated
Voltage Source
Inverter Output for Easy Conversion between 60°/300° and
120°/240° Sensor Phasing Conventions
