Microchip CO and Smoke Detector ICs

CO and Smoke Detector ICs

If you are creating a smoke detector, carbon monoxide (CO) detector or security application, we offer a large portfolio of low-power and cost-effective ICs with a variety of features to meet your design’s requirements. These mix-and-match solutions include low-power ionization and photoelectric smoke detector ICs, CO detector ICs and stand-alone horn driver ICs. Our global technical support team is also available to assist you with your smoke detector design.

Smoke Detector ICs

Our ionization and photoelectric smoke detector ICs are complete solutions for creating a low-cost smoke detector, while our ionization smoke detector front ends can be combined with one of microcontrollers (MCUs) to create a complete design. Whether you are developing an ionization smoke alarm or a photelectric smoke alarm, we offer devices with the following features:

We also provide a selection of integrated devices that include these additional features:
