TMC239A-SA

TMC239 is a low-power two-phase stepper motor driver chip that supports SPI communication and complete protection and diagnostic functions. The external MOSFET can be directly driven to achieve a drive current of 4A. The TMC239 can be used in the control of high motion, high torque motion systems.

Electrical parameters:

◆ 4A drive current can be reached even higher by external MOSFET

◆ The driving voltage is 7-34V, and the driving voltage of 60V can be achieved by the external device.

◆ 3.3 or 5V digital part operating voltage

Interface:

◆ SPI communication interface mode

Features:  

◆ Complete protection and diagnostic functions

◆ Low energy consumption

◆ Mixed attenuation to achieve smooth motor motion

◆ Maximum subdivision adjustment number 16

◆ Programmable ramp control
