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.
These low-power companion devices provide all the necessary analog, interface, and power management functions to build a microcontroller-based CO or toxic gas detector, including:
Ranging from simple to more highly integrated solutions, our horn driver ICs can be used to drive piezoelectric horns in safety, security, toys and other applications.
