MCP8063-E/MD

Overview

The MCP8063-E/MD is a three-phase brushless DC motor driver manufactured by Microchip Technology. It operates within a supply voltage range of 2V to 14V and delivers a continuous output current of 500mA with a peak capability of 1.5A per phase. The device is housed in an 8-pin DFN package measuring 4mm x 4mm x 0.95mm. It supports full-wave sinusoidal drive for smooth operation and functions across an extended temperature range from -40°C to +125°C. The component draws a typical operating supply current of 10mA.

Feature Summary

• Implements 180-degree sinusoidal commutation for quiet, energy-efficient BLDC motor control
• Includes integrated thermal shutdown, overcurrent limiting, and lock protection mechanisms
• Certified to AEC-Q100 automotive reliability standards for harsh environment operation

Applications

• Three-phase brushless DC motors
• Computer cooling fans
• Automotive fan applications

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tape/reel specifications. Ensure the ordering part number matches the required automotive qualification status. Confirm that the DFN-8 footprint aligns with the design layout before finalizing procurement orders.

Selection Notes

Select this component when designing compact systems requiring low-profile packaging and high thermal performance. It is suitable for applications demanding silent operation through sinusoidal drive techniques. Consider its 14V maximum rating and 500mA continuous current limits when sizing the power stage for the target motor load.

Part Context

This device belongs to Microchip's portfolio of motor controllers and drivers designed for motion and ignition systems. It complements digital signal processors like the dsPIC33 series by handling the power stage requirements for three-phase BLDC applications while maintaining a small physical footprint.

Replacement Considerations

The MCP8063T-E/MD is a reel-packaged variant of the same functional device. Verify pin compatibility and electrical parameters if substituting between tube and tape-and-reel configurations.
