2-Phase Stepper-Motor Driver
TLE 4727
Bipolar IC Overview Features • 2 × 0.7 amp. outputs • Integrated driver, control logic and current control (chopper) • Fast free-wheeling diodes • Max. supply voltage 45 V • Outputs free of crossover current • Offset-phase turn-ON of output stages • All outputs short-circuit proof • 5 V output for logic supply • Error-flag for overload, open load, overtemperature Type TLE 4727 Description The TLE 4727 is a bipolar, monolithic IC for driving bipolar stepper motors, DC motors and other inductive loads that operate on constant current. The control logic and power output stages for two bipolar windings are integrated on a single chip which permits switched current control of motors with 0.7 A per phase at operating voltages up to 16 V.
