Product 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.
