DESCRIPTION

The MP6506 is a bipolar stepper-motor driver

with dual, built-in full-bridges consisting of N-

channel power MOSFETs.

It operates from a supply voltage range of 2.7V to

15V, and can deliver motor current up to 500mA

per channel. The internal safety features include

under-voltage lockout and thermal shutdown. An

over-temperature output flag is available to

indicate thermal shutdown.

The MP6506 is available in a 3mm×3mm QFN

package with an exposed thermal pad on the

back.
