AZ, USA, April 12, 2011:- Microchip Technology Inc., a leading provider of microcontroller, analog and Flash-IP solutions, announced that its RE46C190 3V programmable photoelectric Smoke-Detector IC received UL component certification for use in single- and multiple-station smoke alarms, per specification UL 217. This UL-certified component simplifies the certification of smoke-detector products by the UL. The RE46C190 device is the world’s first smoke-detector IC to offer low-voltage operation with programmable calibration and operating modes, which enables the desired modes to be selected and calibrated during manufacturing.

Photoelectric Smoke-Detector ICThe RE46C190’s low operating voltage and low operating current of 8 microamperes typical allows a 10-year operating life for a smoke detector with a lithium battery. Two alkaline batteries may also be used to power the device. Programmable calibration and selection of smoke-detector operating modes provides designers with an easy way to control smoke-detector operation, and enables the use of a single IC to design multiple smoke detectors for different markets and regulatory requirements. The smoke-detector IC also reduces external component counts, since electronic programmability allows the integration of several formerly external components into the device.

Microchip’s smoke-detector device simplifies the design and manufacture of difficult low-voltage smoke detector systems, and the customization of the smoke detector system for particular applications.

The RE46C190 3V programmable photoelectric Smoke-Detector IC is available in a 16-pin SOIC 150 mil. package for $0.94 each, in 10,000-unit quantities. Samples are available, at Microchip sells the RE46C190 Demo Board (part # ADM00344, $199), which enables customers to evaluate the RE46C190 smoke-detector IC in their applications. The board includes a smoke-chamber emulator and RE46C190 application circuit.
