A3966 Description

The A3966 is designed to drive both windings of a two-phase bipolar stepper motor. The device includes two full-bridges capable of continuous output currents of ±650 mA and operating voltages to 30 V. Motor winding current can be controlled by the internal fixed-frequency, pulse-width modulated (PWM), current-control circuitry.

  • Internal fixed-frequency PWM current control
  • Satlington® sink drivers
  • User-selectable blanking window
  • Internal ground-clamp and flyback diodes
  • Internal thermal-shutdown circuitry
  • Crossover-current protection and UVLO protection
