Product Description

DESCRIPTION
The TEA3718 and TEA3718S are bipolar monolithic integrated circuits intended to control and drive the current in one winding of a bipolar stepper motor. 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 or TEA3718S and a few external components form a complete control and drive unit for LS-TTL or microprocessor-controlled stepper motor systems.
■ 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 IN STEPS OR VARIED CONTINUOUSLY
■ THERMAL OVERLOAD PROTECTION
■ ALARM OUTPUT OR PRE-ALARM OUTPUT (see internal table)
