The A3966SLB-T is a dual full-bridge PWM motor driver designed for driving two-phase bipolar stepper motors. It supports continuous output currents of ¬±650 mA and operates at voltages up to 30 V. The device features internal fixed-frequency PWM current control, allowing for precise motor winding current management. Key functionalities include user-selectable blanking windows to prevent false triggering during switching, and optimized low saturation voltage outputs to minimize power dissipation. The A3966SLB-T incorporates several protection features, including thermal shutdown, crossover-current protection, and undervoltage lockout (UVLO). The motor driver is housed in a 16-pin SOICW package, which is lead-free and designed for enhanced thermal dissipation. It operates within an ambient temperature range of -20 to 85 ¬8C, making it suitable for various applications.
