Stepper Motor Driver

The circuits consist of an LS-TTL compatible logic input, a current sensor, a monostable and an output stage with built-in protection diodes. Two TEA3718 ICs and a few external components form a complete control and drive unit for LS-TTL or microprocessor-controlled stepper motor systems.

Key Features

  • Current levels can be selected insteps or varied continuously
  • Designed for unstabilized motor supply voltage
  • Alarm output or pre-alarm output
  • Half-step and full-step mode
  • Built-in protection diodes
  • Bipolar drive of stepper motor for maximum motor performance
  • Wide voltage range 10 to 50 V
  • Thermal overload protection
  • Wide range of current control 5 to 1500 mA
