Overview

Our integrated circuits and reference designs help you create an innovative infusion pump design with accurate sensing technology to better manage fluid dosage and reliable connectivity for data transmission to the cloud.

Design requirements

Infusion pump designs often require:

  • Highly accurate sensing to measure flow, temperature, pressure and air detection.
  • Secure connectivity for telemetry gateways and patient monitoring.
  • Precision fluid pump control.
  • Extended battery life.

TI products may not be used in life-critical medical equipment unless authorized officers of the parties have executed a special contract specifically governing such use. See our Terms of Sale for additional information.
