Overview
The MC33033DWR2G is a monolithic brushless DC motor controller designed for open-loop control of three or four-phase motors. It integrates a rotor position decoder, temperature-compensated reference, frequency-programmable sawtooth oscillator, error amplifier, PWM comparator, and driver outputs. The device operates within a supply voltage range of 10 V to 30 V and includes undervoltage lockout, cycle-by-cycle current limiting, and internal thermal shutdown protection.
Feature Summary
- Integrates active functions for open-loop commutation sequencing including rotor position decoding
- Provides high-current drivers suitable for controlling external three-phase MOSFET bridges
- Includes selectable sensor phasings for flexible configuration with different motor types
Applications
- Open-loop control of three-phase brushless DC motors
- Control of four-phase brushless DC motors
- Brushed DC motor applications using an external MOSFET H-bridge
Procurement Notes
Verify the specific suffix (e.g., G) against official datasheets to confirm package type and compliance status. Ensure the ordering part number matches the required tape-and-reel quantity and lead time requirements from authorized distributors.
Selection Notes
Select this component when open-loop control is sufficient for the application. It lacks separate drive circuit supply pins and fault outputs found in higher-feature counterparts like the MC33035. Suitable for cost-sensitive designs requiring integrated sensing power and driver capabilities.
Part Context
This controller evolved from the full-featured MC33034 and MC33035 series. It retains core active functions but omits features such as brake inputs and dedicated fault signals. It is part of ON Semiconductor's second-generation brushless DC motor control family.
Replacement Considerations
Direct functional substitutes include the MC33033DWG. For applications requiring additional features like fault outputs or separate drive supplies, consider upgrading to the MC33034 or MC33035 series.
