Carbon Monoxide Detector 20-Pin SSOP T/R

The RE46C800 is a low-power CMOS carbon monoxide detector companion IC. The RE46C800 provides all of the analog, interface, and power management functions for a microcontroller-based CO or toxic gas detector. It is intended for use in both 3V and 9V battery or battery- backed applications. It features a boost regulator and horn driver circuit suitable for driving a piezoelectric horn, a 3.3V regulator for microcontroller voltage regulation, an LED driver, an operational amplifier and an IO for communication with interconnected units
