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.
