Microchip Technology Inc, a leading provider of
microcontroller, analog and Flash-IP solutions,
has announced the RE46C190 3V photo smokedetector
IC with horn driver and boost regulator. The
world's first smoke-detector IC to offer low-voltage
operation with programmable calibration and
operating
modes, the
RE46C190 IC
enables the
desired operating
modes to be
selected and
calibrated during manufacturing. This simplifies
smoke-detector design and manufacturing, and
reduces component count, and cost. Additionally, the
IC's low operating current of 8 microamperes typical
enables up to 10 years of operation from a single
Lithium battery. Two alkaline batteries may also be
used to power the RE46C190.
