产品描述

The MP6507 is 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 15V, and can deliver motor current up to 700mA per channel. The internal 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 MP6507 is available in both 16-pin, 5.0mm×6.4mm TSSOP-EP and 3mm×3mm QFN package with an exposed thermal pad on the back.

500mA, 15V, Bipolar Stepper Motor Driver Evaluation Board

The EV6507GF-00A is an evaluation board for the MP6507GF, 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 15V, and can deliver output current up to 700mA 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 EV6507GF-00A is a fully assembled and tested PCB. The input control signals for the MP6507GF 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.
