TCA3727

两相步进电机驱动器双极IC 2-Phase Stepper-Motor Driver Bipolar IC

Description

TCA 3727 is a bipolar, monolithic IC for driving bipolar stepper motors, DC motors and other inductive loads that operate on constantcurrent. 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 0.75 A per phase at operating voltages up to 50 V.

• Fast free-wheeling diodes

• Max. supply voltage 52 V

• Outputs free of crossover current

• Offset-phase turn-ON of output stages

• Z-diode for logic supply

• Low standby-current drain

• Full, half, quarter, mini step
