TI-101 is an integrated circuit of XC06 HV technology. The main application of TI-101 is using in photoelectronic smoke detectors designed for fire identification based on the changes in the optical smoke density and the ambient temperature. This specific usage is provided by a photoamplifier, an ADC, a digital unit, a clock generator and a reference voltage source.
TI-101 operates in conjunction with a control microcontroller or an application-specified integrated circuit. The IC is controlled by a built-in digital unit.
Photoamplifier gain adjustment is available.
There can be selected the following operation modes of the device:
• measurement of smoke optical density mode;
• temperature measurement mode.
«SLEEP» input allows to switch the integrated circuit into the low consumption mode.
An analog-to-digital conversion of the output signal is performed by an 8-bit SAR ADC.
