Pyroelectric infrared technology has been widely used in the fields of transportation and smart home.The quality of the control chip used to receive,amplify and process the input signal of pyroelectric infrared sensor is an important standard to measure the performance of pyroelectric infrared products.This paper designs a pyroelectric infrared control chip used in lighting control,anti-theft alarm and other fields.The chip is a pyroelectric infrared control chip based on 5V 1P3M CMOS technology with low static power consumption and small chip area,with only 8 pins and fewer peripheral devices,which can be sealed with sensors,and has the advantages of miniaturization and effective suppression of RF interference such as mobile phones and Wi-Fi.The simulation results show that the static power consumption of the chip is less than 20 μA,the dynamic power consumption is less than 1 mA,and the chip can work normally in the voltage range of 3.0～5.5 V,and the effective area is about 0.309 mm2.
