M7616

一華半導體股份有限公司 MOSDESIGN SEMICONDUCTOR CORP. PIR CONTROLLER M7616 DC PIR CONTROLLER GENERAL DESCRIPTION The M7616 is a low power PIR ( passive infra-red ) controller LSI designed for battery powered can be used in many application. The chip contains operation amplifiers, comparators, timer ,a voltage regulator, 2 oscillator and control circuits. An CDS device is installed externally to cut off the operation of M7616 during the day time. FEATURES ‧ High noise immunity. ‧ Low stand-by current < 50μA @3.0V ‧ RELAY Driver only. ‧ Adjustable play on duration and latch duration. ‧ CDS input conditionally. ‧ 16 pin DIP or SOP package. APPLICATIONS ‧ PIR light controller, Motion Detector, Alarm system, Auto-door bell. PIN DESCRIPTION PIN 1 2 Pin Name I/O RETG Relay Description Trigger type selection I VDD：Retrigger；VSS：Non-Retrigger O Relay driver output through external NPN transistor. Active high. Delay timing oscillator connect to external RC to adjust output active ─ duration when trigged. output active duration Tx ≈110000xR10xC6。 Trigger latch timing oscillator connect to external RC to adjust latch ─ active duration when trigged. latch active duration Ti ≈110xR9xC7。 ─ Negative power supply I Normally connect to VDD, connect to VSS to reset Timer . Connect to the CDS voltage divider for daytime/night auto detecting,. I When VcdsVR night (VR≈0.2VDD) ─ Positive power supply O 2nd Stage Operation amplifier output I 2nd Stage Operation amplifier negative input I First Stage Operation amplifier positive input I First Stage Operation amplifier negative input O First Stage Operation amplifier output RETG RELAY RR1 RC1 RC2 RR2 VSS RESET M7616P 1 16 1OUT 1IN1IN+ 2IN2OUT VDD 3,4 RR1/ RC1 5,6 RC2/ RR2 7 8 9 VSS RESET CDS 8 9 CDS 11 VDD 12 2OUT 13 2IN14 1IN+ 15 1IN16 1OUT 1/4 2007-03-12 一華半導體股份有限公司 MOSDESIGN SEMICONDUCTOR CORP.
