MC33039DR2

Overview

The MC33039DR2G is a high-performance closed-loop speed control adapter designed for brushless DC motor systems. It enables precise speed regulation without magnetic or optical tachometers. The device operates on a supply voltage range of 5.5 V to 9 V and supports an output current of up to 20 mA. It features three input buffers with hysteresis, three digital edge detectors, a programmable monostable, and an internal shunt regulator. The component functions within a temperature range of -40°C to +85°C and is housed in an 8-pin SOIC package.

Feature Summary

Provides closed-loop speed control for brushless DC motors without requiring external tachometers.
Integrates TTL-compatible inputs with hysteresis for improved noise immunity.
Includes an inverter output to facilitate conversion between different sensor phasing conventions.

Applications

Brushless DC motor control systems
Closed-loop speed regulation applications
Motor driver interfaces

Procurement Notes

Verify the specific suffix (e.g., DR2 vs DR2G) against the manufacturer's official datasheet to confirm package type and compliance status. Ensure the ordering part number matches the required tape and reel specifications. Confirm that the selected variant aligns with the intended operating voltage and temperature requirements for the target application.

Selection Notes

Select this component when designing systems requiring precise speed regulation for BLDC motors without complex sensing hardware. It is suitable for applications needing direct powering from regulated sources or operation via internal shunt regulators. Consider the 8-pin SOIC footprint for surface-mount assembly constraints.

Part Context

This part belongs to the MC33039 series of motor controllers manufactured by onsemi. It is primarily intended for use with the MC33035 brushless motor controller but can be applied in other closed-loop speed control scenarios. The series focuses on cost-effective implementation of digital detection for motor transitions.
