PIR INFRARED REMOTE CONTROL CIRCUIT

UNISONIC TECHNOLOGIES CO., LTD U8803
PIR INFRARED REMOTE CONTROL CIRCUIT
DESCRIPTION
The UTC U8803 is a integrated circuit that design for infrared PIR controlling. It needs only few external components in application circuit. It can be applied as controller of light, electric switching and burglar alarm, and so on.
CMOS IC
DIP-16
FEATURES
High Noise Immunity Output drivable RELAY or TRIAC. contain two OP amps, gain adjustable. Control time adjustable. steady voltage inside output 3.1 V to drive the PIR directly. Integrate zero cross detect, the AC power supply triggers synchronously, lowering the power supply pollution.
Pb-free plating product number: U8803L

FUNCTIONAL DESCRIPTION
CMOS IC
1. The PIR amplifier (the first and second stage Op Amp) amplifies PIR signal. Its multiple can be adjust through resistance and capacitance outside. 2. If the amplificatory PIR signal voltage is higher than VH (Typ 1.8V) or lower than VL (Typ 1.15V), the Window Comparer outputs high level.
