DESCRIPTION

The MP6501A is a stepper motor driver with a

built-in micro stepping translator. It operates

from a supply voltage of up to 35V and can

deliver motor current up to 2.5A. The MP6501A

can operate a bipolar stepper motor in full-,

half-, quarter-, and eighth- step modes. Internal

safety features include over-current protection,

input

over-voltage

protection,

UVLO

and

thermal shutdown. The part has a fixed 3.3V

reference output, which allows it to operate

without any control power supply and work with

any microcontroller. Ron of the switches is as

low as 220mΩ. Current sensing is done by

external resistors.

The MP6501A comes in a space-saving

TSSOP-28 package with exposed thermal pad.
