MC33039DG

Overview

The MC33039DG 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 features three hysteresis input buffers, digital edge detectors, and a programmable monostable timer. It includes an internal shunt regulator for non-regulated sources and an inverter output for sensor phasing conversion. Operating on a single supply from 5.5V to 9V, it supports TTL-compatible inputs and operates within a temperature range of -40°C to +85°C.

Feature Summary

Closed-loop speed control adapter eliminating the need for external tachometers
Three input buffers with hysteresis for enhanced noise immunity
Internal shunt regulator allowing operation from non-regulated voltage sources
Inverter output facilitating easy conversion between different sensor phasing conventions

Applications

Brushless DC motor control systems
Precision speed regulation applications
Systems requiring direct powering from reference voltages

Procurement Notes

Verify the specific suffix 'DG' corresponds to the SOIC-8 package variant when sourcing. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure the application environment remains within the specified -40°C to +85°C operating temperature range. Validate power supply requirements against the 5.5V to 9V operational limits defined in the datasheet.

Selection Notes

Select this component for applications requiring closed-loop BLDC control without complex sensing hardware. It is suitable for designs needing robust noise immunity through hysteresis inputs. Consider its compatibility with the MC33035 controller for integrated solutions. Evaluate the simplified wiring benefits provided by the internal shunt regulator and inverter output capabilities.

Part Context

Part of the MC33039 series, this adapter complements the MC33035 brushless motor controller. It provides essential signal conditioning and logic functions for BLDC drives. The family focuses on cost-effective implementation of closed-loop speed control. It serves as a dedicated interface between Hall effect sensors and the main driver stage.
