A3955SLB SMD Integrated

A3955 is designed to drive one winding of a bipolar stepper motor in microstepping mode. The outputs are rated for continuous output currents up to ±1.5 A and operating voltages up to 50 V. Internal pulse bit modulated (PWM) current control combined with the internal three-bit non-linear digital-to-analog converter allows precise control of the motor current. , half, quarter or eighth step (microstep) modes. Non-linear increments minimize the number of control lines required for microstepping. Microstepping provides increased step resolution and reduces torque variations and resonance problems at low speed.
