Overview

Our integrated circuits and reference designs for continuous positive airway pressure (CPAP) machines help you achieve optimum airway pressure and flow levels while reducing power consumption.

Design requirements

Inventive CPAP machines require:

  • Efficient and precise motor control to maximize patient comfort.
  • Accurate sensing of parameters such as humidity and temperature.
  • Wired or wireless connectivity with smart phones, tablets and computers to enhance user experience.

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.
