Overview
The MC33931VWR2 is a half-bridge motor driver manufactured by NXP Semiconductors, formerly Freescale. It operates within a supply voltage range of 5 V to 28 V and delivers an output current of 5 A. The device features current feedback, sleep mode functionality, and supports surface mount installation in a SOICW-EP-32 package. It functions across a temperature range from -40°C to +125°C with a typical operating supply current of 20 mA.
Feature Summary
- Integrated H-Bridge architecture for brushed DC motor control
- Built-in current feedback mechanism for precise regulation
- Dedicated sleep mode for power conservation
- Thermal protection and diagnostic capabilities
Applications
- Automotive window lift systems
- Seat adjustment actuators
- HVAC blower motor control
- Power tailgate mechanisms
Procurement Notes
Verify the manufacturer designation as NXP Semiconductors, as Freescale was acquired. Confirm the specific suffix 'VWR2' matches the required tape-and-reel packaging format. Ensure the component meets RoHS compliance standards relevant to your region. Cross-reference the datasheet revision to confirm pinout compatibility with existing designs.
Selection Notes
Select this component when a single half-bridge configuration with integrated current sensing is required. It is suitable for applications needing robust thermal performance in automotive environments. Consider the SOICW-EP package for improved heat dissipation compared to standard packages. Evaluate if the 5 A continuous current rating aligns with the motor load requirements.
Part Context
This part belongs to the MC3393x family of motor drivers designed for automotive body electronics. These devices are engineered to replace discrete solutions, reducing board space and complexity. The family offers various configurations including full bridges and multiple half-bridges, tailored for different actuator loads.
Replacement Considerations
Check for direct replacements within the MC3393x series such as MC33931EK or MC33931DR2. Verify package compatibility and electrical parameter equivalence before substitution.
