TEF3718 TEF3718S . HALF AND FULL-STEP MODES . BIPOLAR DRIVE OF STEPPER MOTOR FOR MAXIMUM MOTOR PERFORMANCE . BUILT-IN PROTECTION DIODES . WIDE RANGE OF CURRENT CONTROL : 5 TO 1500 m A . 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 (TEF3718SP) OR PRE- ALARM OUTPUT (TEF3718SSP) STEPPER MOTOR DRIVER POWERDIP 12 + 2 + 2 ORDER CODE : TEF3718DP TEF3718SDP DESCRIPTION The TEF3718 and TEF3718S are bipolar monolithic integrated circuits intended to control and drive the current in one widing of a bipolar stepper motor. The circuits consists of an LS-TLL - patible logic input, a current sensor, a monostable and an output stage with built-in protection diodes. Two TEF3718 or TEF3718S and a few external ponents form a plete control and drive unit for LS-TTL or microprocessor controlled stepper motor systems. PIN CONNECTON MULTIWATT...
