It is designed for load switching to AC mains with a TRIAC or a relay in 3 wire systems. A conventional PIR sen- ÿ Low power consumption sor connects directly to the PIR input. The pull-down resistor and ÿ Temperature compensation input DC decoupling circuitry are integrated on chip. The PIR signal is ÿ Adjustable soft on/off switching (fading) converted to a 15 bit digital value. External potentiometers or re- ÿ Dimmer function sistors are used to set the operating parameters for sensitivity, ÿ Inductive load switching on-time, brightness, fade, daylight sensor and environment tem- ÿ Capacitive load on/off switching perature correction. The corresponding voltage levels are con- ÿ Four quadrant TRIAC driver verted to digital values with a 4 bit resolution. All signal process- ÿ Suitable for 115V/60Hz and 230V/50Hz applications ing is performed digitally. ÿ Low TRIAC switching noise ÿ – 40°C to + 70ºC operating temperature Related products: ÿ SO20w package M2006: PIR Motion detector M2008: PIR Light controller for two-wire applications M2011: PIR Light controller APPLICATION ÿ Outdoor and indoor motion sensor lights ÿ High end lighting switches ÿ Automatic bedroom night lights ÿ Energy saving BLOCK DIAGRAM VDD PACKAGE Pin Name Description 1 BRIGHT Set maximum brightness of light 2 FADE Set fading time of light 3 SENSE Set sensitivity threshold for switching light on 4 ON _ TIME Set light on time 5 TCOMP Temperature compensation input 6 DARK Dark mode input, connected to LDR/Photodiode 7 SWIN ON-AUTO-OFF select input 8 VSW Input voltage sensor 9 ACIN Mains power in (rectifier) 10 AVDD Analog supply 11 TEST Reserved test mode, connect to GND 12 TOG Selects toggle mode 13 RETRIG Selects retrigger mode 14 PIRIN PIR sensor input 15 AGND Analog ground 16 GND Digital ground 17 RELAY LED output, push-pull 18 TRIAC TRIAC gate signal, push-pull 19 VDD Digital supply 20 CLOCK Set oscillator frequency BRIGHT 1 20 FADE 2 19 SENS 3 18 ON_TIME 4 17 TCOMP 5 16 DARK 6 15 SWIN 7 14 VSW 8 13 ACIN 9 12 AVDD 10 11 CLOCK VDD TRIAC RELAY GND AGND PIRIN RETRIG TOG TEST AVDD ACIN PIRIN + A Amp. _ VDD DSP VREG Filter D AGND N VDD SENS VSW BRIGHT FADE ADC control ONTIME TRIAC TCOMP ϑ RELAIS VDD CLOCK DARK VDD OSC VDD TOG VDD GND 96 Ph SWIN RTRIG GND Note ELMOS Semiconductor AG (below ELMOS) reserves the right to make changes to the product contained in this publication without notice.
