How does ADI stepper motor control improve the accuracy and reliability of modern infusion pumps?

As modern infusion pump system demands for smooth motion, quiet operation, reliable occlusion detection, and energy efficiency. Analog Devices addresses these demands through its ADI Trinamic™ motor and motion-control solutions that combine advanced drive technology and integrated diagnostics. Features such as silent voltage mode chopping, sensor-free load detection, and adaptive current control allow designers to reduce system complexity while improving performance, safety, and battery life across various pump architectures.

ADI’s TMC5262 stepper motor controller and driver represents the latest generation of ADI Trinamic motion-control technology. Advanced technologies such as StealthChop+, StallGuard+, CoolStep+, µDcStep, and TriCoder , work together to enable safer, quieter, and more energy-efficient infusion pump designs.

The result is improved patient safety, drug efficacy, and regulatory compliance.
