The negative half wave is shorted to VSS. The rectifier operates with capacitive and resistive voltage dropper circuits. The maximum peak current must be limited to 300mA. The average current must be less than 20mA. 4.3 Voltage Regulator The voltage regulator acts as a Zener diode between VDD and VSS. An external smoothing capacitor is required between the VDD and VSS pins. The device can tolerate 50Hz ripple on its supply, because the PIR signal is filtered with a second order digital low pass having a low cutoff frequency. The voltage regulator can shunt currents up to 20mA continuously. 4.4 Oscillator The IC contains an on chip oscillator with frequency set to 57 kHz. All timing signals and cutoff frequencies of the digital filters are derived from this frequency. 4.5 Input amplifier and A/D Converter The PIRIN input has an internal pull-down resistor and DC decoupling circuitry. The signal voltage on the PIR input is converted to a 15 bit digital value. ELMOS Semiconductor AG Specification 7 / 16 03SP0383E.00 16/07/07 E910.84 4.6 Band-Pass Filter A 2nd order digital Butterworth band-pass filter eliminates unwanted frequency components above and below the band of interest (0.4Hz ... 7Hz). 4.7 Threshold Comparator The output signal from the band pass filter is digitally rectified and its peak value compared against a threshold value calculated from the voltages on the SENS and TCOMP inputs. Whenever the PIR signal exceeds the threshold, the load is switched on. The threshold comparator is disabled for 1.5s after the load has been switched off. In case, that the fade time has been set to a value bigger than zero, the threshold comparator ignores the signal from the PIR input during he fade time and for an additional 1.5s after the light has been completely switched off. 4.8 Parameter Settings The E910.84 provides for six inputs, which are used to define the operational parameters. The voltages applied on these inputs are converted to 4 bit digital values. SENS: Set the sensitivity threshold required to generate a trigger condition. Sixteen different threshold values are possible. The threshold value internally recalculated with the temperature compensation factor. Refer to table 6. BRIGHT: Sets the maximum brightness of the light. The brightness levels are divided into 15 equal steps. One step corresponds to 90*(1- 1/16) degrees phase angle. FADE: Sets the time it takes to fade the light from off to full brightness. On and off fading takes equally long. Refer to table 6. ON-TIME: Sets the time the light remains on. Refer to table 6. TCOMP: A temperature dependent resistor network can be connected to this pin. The temperature voltage, in the range from VSS to VDD/4 is converted to a set of threshold multiplication factors. The voltage on this pin must decrease as the temperature increases, so a NTC resistor (β=4500) is used. At 37°C, the TCOMP voltage should be between VDD*7/128 and VDD*9/128 for maximum detection sensitivity. Temperature compensation may be disabled by connecting TCOMP to VSS. The temperature compensated threshold voltage is the comparator threshold multiplied with the Tcomp factor in table 6.

Brightness control is achieved with firing the TRIAC at different phase angles of the mains voltage. The voltage sense input is monitored and load switching can only happen, if the voltage on this input is close or above VDD or close or below VSS. The maximum brightness = minimum phase angle for the load switching is set with an external voltage divider. This ensures that the electronics have enough power supply when switching the load to maximum brightness in 2 wire operation. 4.10 RELAY Output The RELAY output is an active high output and changes state at the start of the fading cycle. 4.11 LED Output The LED output is an open drain output that is active (16ms) when the PIR signal exceeds the set threshold. A capacitor charged with a limited current from the generated VDD supply is discharged through a LED connected to the LED output of the device. 4.12 Controller: Modes of Operation Behaviour of the light controller is separated in to two modes; switch from Off To Set Brightness (OTSB) or switch from Set brightness To Full Brightness (STFB). The two modes are selected by applying a specific voltage on the TOG input. All operating modes are determined by four inputs in table 7. ELMOS Semiconductor AG Specification 9 / 16 03SP0383E.00 16/07/07 E910.84 Pin Name SWIN TOGGLE 1 RETRIG DARK 2 Description Selects the ON-AUTO-OFF mode. VDD: light permanently ON (to set brightness) VSS: light permanently OFF Floating: PIR sensor mode (AUTO) Mains Toggle Mode If enabled a mains On – Off - On will switch the load permanently to set brightness if DARK. VDD *3/16 or greater OTSB mode, mains toggling enabled. VDD *5/32 STFB mode, mains toggling enabled. VDD *3/32 STFB mode, mains toggling disabled VDD *1/16 or less OTSB mode, mains toggling enabled. Re-trigger Mode VDD or floating: The timer for the on-time is restarted whenever movement is detected. VSS: The light will stay on for the on-time. Movement detection is ignored during this period. Typically connected to a Light Dependant Resistor (LDR) or photo transistor, to prevent the light from switching on during daylight conditions. VDD: Enable switching of the light VSS: Disables switching of the light Do not leave this input floating. Table 7: Operational settings 1 2 The toggle mode is not cancelled by setting SWIN input to VSS, although the light will be switched off DARK is ignored when the light is ON in PIR sensor mode (AUTO). 5 Operation 5.1 Power-up Mode Whenever the circuit is powered up, the light is switched on for the selected on-time duration. The DARK input is ignored on power-up, to allow the user to verify the installation during daylight conditions. 5.2 Trigger condition The threshold voltage (SENS) is multiplied with the Tcomp factor (refer to table 6), to obtain a temperature dependent threshold voltage. When the PIR signal exceeds this calculated threshold voltage, a trigger condition occurs. 5.3 Conditions for Switching the Light ON (AUTO mode, OTSB mode) If a trigger condition occurs and the DARK input is high, the light will be switched on. The light’s brightness will increase to the selected BRIGHTNESS within the selected FADE TIME. The RELAY output is activated at the start of the fading-on cycle. The relay will remain on and the light at the set BRIGHTNESS for the duration set by the ON-TIME input. The DARK input is ignored during this time. If the TOGGLE MODE is enabled, the light can also be switched on by toggling the mains ON-OFF-ON within 3 seconds. In this mode, the PIR input is ignored; the DARK input will switch the light ON or OFF. This mode is disabled by disconnecting the mains for a few seconds. ELMOS Semiconductor AG Specification 10 / 16 03SP0383E.00 16/07/07 E910.84 5.4 Conditions for Switching the Light OFF (AUTO mode OTSB mode) The light fades to zero after the selected ON-TIME has elapsed, within the selected FADE TIME. The RELAY output is switched off at the start of the fading-off cycle. 5.5 Conditions for Switching the Light ON (AUTO mode, STFB mode) If the DARK input is high, the light will be on at the set BRIGHTNESS. If a trigger condition occurs, the light will be switched to full brightness. The light’s brightness will increase to maximum within the selected FADE TIME. The RELAY output is activated at the start of the fading-on cycle. The relay output will be active and the light remains at full brightness for the duration set by the ON-TIME input. If the TOGGLE MODE is enabled, the light can also be switched on to the set brightness by toggling the mains ON-OFF-ON within 3 seconds. In this mode, the PIR input is ignored; the DARK input will switch the light ON or OFF. This mode is disabled by disconnecting the mains for a few seconds. The RELAY output is switched off at the start of the fading-off cycle. 5.6 Condition for Switching the Light to set brightness (AUTO mode, STFB mode) The light will fade within the selected FADE TIME to the set BRIGHTNESS after the selected ON-TIME has elapsed.
