MC33486DH

Overview

The MC33486DH is a fully integrated motor driver IC designed for brushed DC motors. It features a power MOSFET technology with a high-side output configuration. The device operates within an 8V to 28V supply and load voltage range, supporting up to 10A output current. It integrates both control logic and power stages in a single package. The component supports parallel interface communication and is rated for junction temperatures up to 150°C. It utilizes a 20-HSOP surface-mount package with exposed pad for thermal management.

Feature Summary

• Fully integrated driver combining control and power stages
• High-side output configuration for brushed DC motors
• Integrated diagnostics and protection mechanisms
• Supports operation in harsh automotive environments

Applications

• Automotive seat adjustment systems
• Power window actuators

Procurement Notes

Verify the specific suffix against official NXP documentation to confirm pinout and electrical characteristics. Confirm RoHS compliance status as historical data indicates potential non-compliance for older revisions. Check for active production status or last-time buy notices. Ensure the supplier provides valid traceability documents. Validate that the package type matches the design requirements for thermal dissipation.

Selection Notes

Select this component when a compact solution for high-current brushed DC motor control is required. It is suitable for applications needing integrated protection and diagnostics without external discrete components. Consider the thermal performance of the HSOP package with exposed pad for heat dissipation. Verify compatibility with the system's voltage range and interface requirements.
