MC33039D Description

Short technical summary and product information.

The MC33039D from ON Semiconductor is a high-performance closed-loop speed control adapter designed for brushless DC motor control systems. This IC enables precise speed regulation without the requirement for a magnetic or optical tachometer. It integrates three input buffers with hysteresis for noise immunity, three digital edge detectors, a programmable monostable, and an internal shunt regulator.

 

Key features include TTL compatible inputs with hysteresis, operation down to 5.5 V for direct powering from compatible controllers, and an inverter output for easy conversion between sensor phasing conventions. The device is available in an 8-SOIC surface mount package.

 

This motor driver adapter is primarily intended for use with the MC33035 brushless motor controller but can be cost-effectively implemented in many other closed-loop speed control applications requiring precise speed regulation.
