Product overview

Description

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.

  • All 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
