Infusion pumps are crucial devices for precise drug delivery in clinical settings, with their core function being the precise and constant control of drug flow rate. To address the back electromotive force generated by the stepper motor drive system and the signal ripple interference from the precision pressure sensor, we offer high-performance transient overvoltage suppression and power integrity protection solutions. These solutions effectively absorb voltage fluctuations during motor commutation, prevent parameter drift in logic circuits caused by electromagnetic interference, and ensure millisecond-level precision in injection even during long-term continuous operation, providing robust safety assurance for critical care and long-term chemotherapy.
