1 TT000 PIR / Microwave sensor control chip Outline TT000 is a CMOS chip designed to human infrared sensor control integrated circuits; it is a kind of high-performance sensor signal processing integrated circuit (IC) which together with PIR sensor and outward elements to constituent PIR switch. It can automatically and quickly open such devices as incandescent lamps, fluorescent lamps, buzzers, automatic valves, electric fans, dryers and automatic hand-washing facilities. IC is especially suitable for enterprises, hotels, shopping malls, warehouses, passages or corridors of houses, automatic lights, lighting systems and alarm systems. It can use PHOTO transistor or CDS application. The chip is equipped with amplifiers, comparator, timer, control circuits, system oscillator, and output timing oscillator. Its PIR sensor or MICROWVE sensor detects infrared power variation induced by the motion of a human body and transforms it to a voltage variation. If PIR output voltage variation conforms to the criteria, then the lamp is turned on with an adjustable duration. Characteristic Voltage operating range:.8v ~ 6.0V Low power CMOS technology(ideal for battery operated PIR devices) CMOS high input impedance operational amplifiers Bi-directional level detector / Excellent noise immunity Built-in Power up disable & output pulse control logic Dual mode : retriggerable & non-retriggerable Package for 6 SOP pplications Human infrared sensor lights utomatic energy-efficient lighting occasions like garden, garage, hallway, stairs Monitoring, alarm, doorbell system like home, shops, offices, factories utomatic switching system like exhaust fans, ceiling fans 07// Page of Version:.
