TEA3718 Datasheet PDF - ST Microelectronics

●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.
