    • Provides precise current regulation, supporting higher current per channel for demanding thermal management applications.

Advanced Features

  • True Synchronized Multi-Actuator Control with Hall-Effect and Potentiometer Feedback
    Control two linear actuators at once, perfectly synchronized using real-time feedback from Hall-effect sensors or potentiometers. Achieve accurate, repeatable movement—ideal for lift desks, robotics, and custom automation where precise alignment is critical. Advanced closed-loop control ensures both actuators always move together, auto-correcting drift and supporting programmable endpoints for advanced automation.
  • Motion Presets & Programmable Position Control
    Store and recall multiple preset positions directly on the controller. Easily automate movement to frequently used locations with the push of a button or simple command, streamlining repetitive tasks and complex automation sequences.
  • Integrated Precision Current Sensing & Regulation
    On-board current sensing across high-side MOSFETs (IPROPI) for each half-bridge
    ±3.5% sense accuracy at maximum current
    Optional support for external current sense resistors
  • Flexible Logic & Programmable Control
    Separate logic supply (VCC) for system compatibility
    Programmable output rise/fall time for optimal EMI performance
    Programmable fault recovery for custom protection response
    Supports 1.8V, 3.3V, and 5.0V logic-level inputs
  • Ultra-Low Standby Power
    Sleep mode draws less than 3 µA for battery-powered or always-on applications
  • Comprehensive Protection Suite
    Supply undervoltage lockout (UVLO)
    Charge pump undervoltage (CPUV)
    Overcurrent protection (OCP)
    Overtemperature/thermal shutdown (OTSD)
    Real-time fault output (nFAULT) pin for system monitoring
  • Unique 48 V compatibility: Most competing controllers only support up to 24 V; this unit supports the full range up to 60V.
