Carbon Monoxide Detector Companion IC

Features:

Description:

• Low Quiescent Current

• Operation from 2V or 12V

• 9.8V Boost Regulator

• Horn Driver

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.

• LED Driver

• 3.3V Regulated Voltage for Microcontroller

Operation

• Internal Operational Amplifiers:

- ±1 mV Input Offset Voltage

- Rail-to-rail Input and Output

- 10 kHz Gain Bandwidth Product

- Unity Gain Stable
