DESCRIPTION

The MP6508A is a bipolar stepper motor driver

with dual, built-in full-bridges consisting of Nchannel power MOSFETs. The device operates

across a 2.7V to 18V input voltage (VIN) range

and can deliver a motor current up to 1.2A per

channel.

Internal safety features include over-current

protection (OCP), under-voltage lockout

protection (UVLO), and thermal shutdown. The

MP6508A provides a fault output flag to indicate

OCP and thermal shutdown.

The MP6508A is available in a QFN-16

(3mmx3mm) package with an exposed thermal

pad on the backside.
