TEA3718 Stepper motor driver Features Half-step and full-step mode Bipolar drive of stepper motor for maximum motor performance Power DIP 12+2+2 SO20 Built-in protection diodes Wide range of current control 5 to 1500 mA Wide voltage range 10 to 50 V Designed for unstabilized motor supply voltage Current levels can be selected insteps or Multiwatt 15 varied continuously Thermal overload protection Alarm output or pre-alarm output Figure 1. Block diagram Applications Motor winding The TEA3718 is a bipolar monolithic integrated circuit intended to control and drive the current in OUT A OUT B one winding of a bipolar stepper motor. COMPARATOR Description INPUT ALARM PHASE The circuits consist of an LS-TTL compatible logic (TEA3718SP) PULSE TIME PRE-ALARM input, a current sensor, a monostable and an TEA3718 (TEA3718SFP) output stage with built-in protection diodes. Two IN0 IN1 TEA3718 ICs and a few external components SENSE RESISTOR form a complete control and drive unit for LS-TTL REFERENCE or microprocessor-controlled stepper motor systems. Table 1.
