PIR Motion Detector
This IC senses the signal from a passive infrared (PIR) sensor to serve as a motion detector in security systems. The analog section provides the sensor amplifier, low pass filter and window comparator functions. The digital section includes logic to minimize false alarms and “self test” functions to insure the system is operating correctly. Its operating current is extremely low to support battery operated systems.
Features:
Wide Supply Range (2.4V to 6.0V)
Low Active Current (< 5uA)
Dedicated PIR Sensor Amplifier
Switched Capacitor Low Pass Filter
Window Comparator
RC Timer
Temperature Range = -40°C to +70°C
