A3967SLB,Microstepping Motor Driver IC,24-Lead SOIC

The A3967SLB is a complete microstepping motor driver IC designed for precise control of bipolar stepper motors. With built-in translator functionality, it eliminates the need for complex phase-sequence programming. The IC supports full-, half-, quarter-, and eighth-step resolutions, making it ideal for applications requiring high precision and smooth motor operation.

Capable of operating at up to 30V and delivering +/-750mA of continuous output current, the A3967SLB ensures reliable performance in demanding conditions. The IC includes advanced features such as fixed off-time PWM current regulation, automatic current-decay mode selection, and integrated protections like thermal shutdown and UVLO. Its 24-lead SOIC package with batwing tabs provides superior heat dissipation for efficient thermal management.
