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.

Features

■ Half-step and full-step mode

■ Bipolar drive of stepper motor for maximum motor performance

■ 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 varied continuously

■ Thermal overload protection

■ Alarm output or pre-alarm output

Applications

The TEA3718 is a bipolar monolithic integrated circuit intended to control and drive the current in one winding of a bipolar stepper motor.
