MP6509

1.2A Bipolar Stepper Motor Driver with Current Attenuation

Active

Datasheet

Description

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.

MP6509 20-pin进来,6.5 mmx6.4mm TSSOP-EP package with an exposed thermal pad on the backside.

Evaluation Tools

EV6509-F-00A Evaluation Kit 1.2A, 18V, Bipolar Stepper Motor Driver Evaluation Board

The EV6509-F-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.

The device operates from a 2.7V to 18V supply voltage range, and can deliver output currents up to 1.2A per channel. The safety features
include sink and source current limits implemented with external sensors, undervoltage lockout (UVLO), and thermal shutdown.
An over-temperature output flag is available to indicate thermal shutdown.

The EV6509-F-00A is a fully assembled and tested PCB. The input control signals for the MP6509 are applied through the connector, or
generated on the board. The board can drive a bipolar stepper motor with both full step and half-step mode. It also can drive two independent DC motors.
