Key Features

  • Stepper motor controller supporting 10 V to 46 V supply range for flexible deployment in industrial and robotics applications
  • 1.2 A maximum output current per phase for reliable bipolar stepper motor drive in precision motion systems
  • 20-pin PLCC (S-PQCC-J20) plastic package with epoxy body enabling space-efficient surface-mount board assembly
  • Single-function dedicated stepper motor control IC simplifying drive circuit design and reducing external component count

Applications

The UC3717AQTR is designed for precise bipolar stepper motor control in industrial automation, CNC machinery, and robotics where accurate position control and reliable high-voltage motor drive are essential. Its 10 V to 46 V supply compatibility enables direct integration with standard 24 V and 36 V industrial power rails without additional regulation. The 1.2 A output current rating makes it suitable for driving small to medium bipolar stepper motors in printers, scanners, and laboratory automation equipment.
