UT8803G-D16-T

UNISONIC TECHNOLOGIES CO., LTD UT8803 PIR INFRARED REMOTE CONTROL CIRCUIT DESCRIPTION The UTC UT8803 is an 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 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.

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. 3. The Pulse Width Detector detects the Window Comparer’s pulse width, if the high pulse width is more than 768*TTb, this pulse is in effect, and the RELAY or the traic is triggered. Otherwise, it is ignored. 4. When an availability PIR signal is detected, the RELAY outputs high level, and the TRAIC outputs pulse, and the Counter starts to count, but if a new availability PIR signal appears, the Counter restarts to count. After 245760*TTci, the RELAY and TRIAC stop output. 5. Pin CDS connect a CDS, it can control pin RELAY to keep low level in the daytime. 6. When the AC power crosses zero line, the Zero Cross Detector generates a pulse, and permits the TRIAC to be triggered, after 32*TTb.
