The MP6509 is a bipolar stepper-motor driver with dual, built-in full-bridges consisting of Nchannel 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 MP6509 comes in 20-pin, 6.5mmx6.4mm TSSOP-EP package with an exposed thermal pad on the backside.
