Product Description

The MP6518 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 1.5A. The MP6518 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 300mO. Current sensing is done by external resistors. The MP6518 comes in a space-saving TSSOP-28 package with exposed thermal pad.

2.5A, 35V Bipolar Stepper Motor Driver Evaluation Kit

The MP6501AGF demo board is a customized evaluation board for a stepper motor driver with a built-in micro-stepping translator.

The MP6501AGF demo board operates from a supply voltage of up to 35V and delivers motor current up to 2.5A. It operates a bipolar stepper motor in full-, half-, quarter-, eighth-, and sixteenth- step modes by setting the MS3, MS2, and MS1. The input control signals and reference voltage are applied through the connector or generated on the board.
