Smoke-Detector IC from Microchip offers low-voltage operation with programmable operating modes and calibration
Microchip announced the RE46C190 3V photo smoke-detector 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 optimum operating modes to be selected and calibrated during manufacturing. This simplifies smoke-detector design and manufacturing, as well as reducing component count and cost. Additionally, the IC’s low typical operating current of 8 microamperes enables up to 10 years of operation from a single Lithium battery. Two Alkaline batteries may also be used to power the RE46C190.
ProgThe addition of the new low-voltage smoke-detector IC expands Microchip's broad line of PIC® microcontrollers, horn drivers, smoke-detector ICs, and signal-chain and power-management devices which support a range of smoke-detector applications, from simple residential detectors to programmable commercial systems.
