Pyroelectric infrared sensor controller PIR0004

Pir0004 is a special chip for infrared induction control of human body designed for LED lighting, which adopts advanced COMS
Process manufacturing, high-performance power supply voltage stabilizing circuit, operational amplifier, voltage comparator and timer are built in the chip.
Control circuit, system oscillator, and output timing oscillator. PIR sensor will generate red light from human activities.
The change of external signal is detected and converted into the change of voltage signal according to the amplitude of output voltage signal.
Decide whether LED lighting is on or not;
Characteristic
? working voltage: 3.6V ~ 5.5V, built-in voltage regulator: 3.0V ± 0.36v.
? built in system clock frequency: 16KHz
? working current: < 20ua (Vbat = 4.5V, no load)
? provide external RC set output delay time for 3 seconds to 110 adjustable
? 1 second stabilization time and 16 second preheating time (preheating time) after power on
? when the output is from on to off, there is a signal inhibit time of 1 second.
