1.2A BIPOLAR STEPPER MOTOR DRIVER

The MP6508 is a bipolar stepper-motor driver with dual, built-in full-bridges consisting of N-channel power MOSFETs. It operates from a supply voltage ranging from 2.7V to 18V and can deliver motor current up to 1.2A per channel. The Internal safety features include over-current protection(OCP), under-voltage lockout protection(UVLO) and thermal shutdown. A fault output flag is available to indicate OCP and thermal shutdown. The MP6508 comes in both 16-pin, 5.0mmx6.4mm TSSOP-EP and 4mmx4mm QFN package with an exposed thermal pad on the backside.
