Status: In Production
The RE46C191 is a low voltage, low
current programmable photoelectric smoke detector IC. This circuit will provide all the required
features for a photoelectric smoke detector with minimal external components. Programmable setup, calibration and feature
selection are the key to reduced component count and reduced manufacturing
costs. The boost regulator insures
proper operation of the infrared diode and the piezo horn under low battery
conditions. The RE46C191 was designed for use in smoke
detectors that comply with Underwriters Laboratory Specification UL217.
The demo board is a complete stand-alone smoke detector application with a smoke chamber emulator. The demo board allows evaluation of all the functions of the RE46C190. Key test points of the device are available at the bottom edge of the demo board. It is designed for battery operation using a CR123A battery or can be operated using a power supply. The RE46C190 application circuit is on the...
