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.
主要特性
- 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
