If the PIR output voltage variation conforms to criteria, the lamp is turned on for an adjustable duration. CDS can enable or disable output with external voltage divider.

Reset input, active low. Ground Schmitt, connected to a CDS voltage divider for daytime/night auto-detection. Low input to this pin can disable PIR input. CDS should be connected to VCC when not using this function. RELAY drive output through an external NPN transistor, active high. The output active duration is controlled by the HT pin Power supply Schmitt input/open drain output, pulse width detection* Schmitt input/open drain output, hold time, external RC to set output ON time duration. Use a VR to make variable ON time. Power on reset, reset the chip in about 40s after power on with an external RC. Schmitt, force on control input, active low. Internal voltage regulator output, 3.6V with respect to ground. Connected to the drain of PIR sensor Functional description Force On Function Pulse width detection (PWD) or Noise rejection circuit PT8A2620 & & Pulse width detection can be used to filter the noise in order to prevent error trigger from the system. The default criteria of the width must be more than 400ms which can be set with an external RC. Hold time (HT) ON POR RST Hold time, in other word, the output active duration, it can be set with an external RC. One various resistor can be used to changed the related output duration. Force on function Power on Reset (POR) The IC can force the controlled lamp to on state by turning off the power supply for a brief period of time. During this brief power interruption, the power to the IC must be maintained. Shown in the schematic, with ON input discharged to low while RST maintains at high, the lamp output can be set to on until a RST input is low (longer period of power down). This feature may cause not intended lamp on situation during brief power interruption. Tie ON to VCC to disable this feature. The external PIR sensor requires a period of up to 40 seconds to stabilize, so a power on reset circuit is required to ensure proper operations. During this power on reset period, the lamp is on to indicate proper operation. Retrigger If another PIR signal is attained with valid duration, the circuit will be retriggered, and the hold time will be restarted from this time.
