Ny chip kan lugte røg

Microchip lancerer røgdetektor-chip, der kan operere ved lave spændinger og understøtter programmerbare operative modes og kalibrering (in english).

Microchip announces 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.

Programmable calibration and selection of smoke-detector operating modes provides designers with an easy way to control smoke-detector operation, and enables a single IC to be used to design smoke detectors for different markets and regulatory requirements.  Electronic programmability also eliminates the need for a number of external components, which in turn reduces the costs associated with manufacturing and inventory.

The 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.
The RE46C190 smoke-detector IC is available in a 16-pin SOIC 150 mil package.
