The A3967SLBTR-T is a microstepping motor driver designed for bipolar stepper motors, capable of operating in full, half, quarter, and eighth-step modes. It supports an output drive voltage of up to 30 V and can handle continuous output currents of ±750 mA, with peak currents reaching ±850 mA. The device features automatic current-decay mode detection and selection, allowing for mixed, fast, and slow decay modes, which contribute to reduced motor noise and improved step accuracy. This driver includes built-in protection mechanisms such as undervoltage lockout (UVLO), thermal shutdown, and crossover-current protection, ensuring reliable operation under various conditions. The A3967SLBTR-T operates with a logic supply voltage range of 3.0 to 5.5 V and is packaged in a 24-pin SOIC format, which includes internally fused pins for enhanced thermal dissipation. The device is suitable for applications where a complex microcontroller is not available or is overloaded, simplifying the implementation process.
The A3967 simplifies stepper motor control. Its integrated translator eliminates complex programming, while automatic current decay selection and synchronous rectification ensure quiet and efficient operation in full-, half-, quarter-, and eighth-step modes.
