Product Overview
HM4002 is a low-power pyroelectric infrared sensor signal processing chip, which can be matched with infrared sensor unit Simple load sensing ON/OFF and delay timing function control; at the same time, the chip built-in high-precision stable LDO 2.6V output can provide Red power supply for external sensors; built-in first-level high-gain fixed 30dB amplifier, with external adjustable second-order band-pass filter amplifier A high-reliability infrared human body sensing signal processing chip that can achieve up to 75dB low-band-pass signal amplification.
Chip characteristics
◇ Working voltage: 2.8-5.5V
◇ Low standby power consumption: 18-22uA (very suitable for battery applications);
◇ Built-in LDO output voltage 2.6V @max 5mA can directly power PIR;
◇ Fixed 2S internal block time to simplify the periphery and suppress interference;
◇ Light control enable function (photoresistor);
◇ The delay time can be adjusted by connecting a single capacitor;
◇ Built-in first-level amplifier, the most simplified peripheral components can be less than 8;
◇ Simple peripheral PCB layout can be completed on a single panel, with low cost;
◇ Continuous and discontinuous trigger mode chip classification optional
Practical application
◇ Very suitable for simple peripheral battery applications. LED lighting sensor lights (solar lithium battery triangular wall light, dry battery sensor Night lights, battery induction corridor lights, etc.);
◇ Various automatic induction switch application systems such as automatic lighting fixtures, automatic doors, washing basins, dryers, alarms, etc.;
◇ Human body infrared and microwave induction switch signal processing related circuit applications;
