• On-chip regulator.
• Adjustable output duration.
• CDS input.
• 30 second warm-up.
• ON/AUTO/OFF selected by MODE pin.
• Override function.
• Auto-reset if the ZC signal disappears for over 3 second.
• 16 pin DIP or SOP package.
APPLICATIONS 產品應用
• PIR light controller, Motion Detector, Alarm system, Auto-door bell.
