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.
◆ 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
◆ SPI communication interface mode
◆ Complete protection and diagnostic functions
◆ Low energy consumption
◆ Mixed attenuation to achieve smooth motor motion
◆ Maximum subdivision adjustment number 16
◆ Programmable ramp control
