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.
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
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.
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.
