EZ2130¶
Product Profile¶
EZ2130 is a high-performance two-phase stepper motor driver chip with a standard SPI interface and a simple step/dir interface. Very low noise, high load driver does not lose step.
Features Highlights¶
- Up to 256 subdivisions;
- Support SPI interface control;
- Do not lose step when driving under high load;
- Logic voltage: 3.3V/5V;
- Input voltage range: 12V/24V DC;
- Motor operating current 1.2a (peak 2A) can be adjusted;
- Spreadcycle ensures that the stepper motor has a smooth transition without dead zone current when passing zero.TMC2130 stepper motor driver chip has almost no jitter;
- StealthChop can drive the motor to work under extremely quiet sound, so it can be controlled the noise of the motor is below 10dB, which is much lower than that of the traditional current controllerType;
- SpreadCycle PWM chopped mode is automatically divided between slow and fast attenuators setting up a hysteresis attenuation function, the average current reflects the configured normal current in sine there will be no transition period at the zero crossing of the sine, which reduces the current and torque fluctuations that make the current waveform more similar to the sine wave. Compared with the traditional constant chopper mode of SpreadCycle PWM, the motor operates more smoothly and stably;
