DESCRIPTION

The EV6509GF-00A is an evaluation board for

the MP6509GF, a bipolar stepper motor driver

with dual, built-in full-bridges consisting of N-

channel power MOSFETs.

It operates from a supply voltage range of 2.7V

to 18V, and can deliver output current up to

1.2A per channel. The safety features include

sinking and sourcing current limits implemented

with external sensors, under-voltage lockout

and thermal shutdown. An over-temperature

output flag is available to indicate thermal

shutdown.

The EV6509GF-00A is a fully assembled and

tested PCB. The input control signals for the

MP6509GF are applied through the connector

or generated on board. It can drive a bipolar

stepper motor with both full step and half step

mode. It also can drive two independent DC

motors.
