Infrared pyrolysis control module based on TM2291

TM2291 has the same function as BISS0001 . Its quiescent current is 1uA-3uA and low power consumption. In addition, it can work normally at -20 degrees. The power consumption of the detector made by TM2291 is about 10 uA lower than that made by BISS0001.

1. Overview TM2291 is an infrared sensing signal processor, manufactured using CMOS technology, in SOP16 packaging, and applied to pyroelectric infrared switch circuits. This product has excellent performance, ultra-low power consumption, is suitable for battery (dry cell, lithium battery, etc.) power supply, has reliable quality and simple peripheral circuit.
