Product Description

The EV6508-F-00A is an evaluation board designed for the MP6508GF, a bipolar stepper motor driver with dual, built-in full bridges
consisting of N-channel power MOSFETs.

The MP6508 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 EV6508-F-00A is a fully assembled and tested PCB. The input control signals for the MP6508 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.

Product Features

  • Wide 2.7V to 18V Input Voltage Range
  • Over-Current and Over-Temperature Indication
  • Alternative Input Control Signals (External or Generated on Board)


1.2A Bipolar Stepper Motor Driver

The MP6508 is a bipolar stepper-motor driver with dual, built-in full-bridges consisting of N-channel 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. The MP6508 comes in both 16-pin, 5.0mmx6.4mm TSSOP-EP and 4mmx4mm QFN package with an exposed thermal pad on the backside.
