Repetition time is the time between two separate measurements. Integration time is the duration for one measurement. ALS high sensitivity modes are 1010 and 1011 with an increased integration time of 400ms. In PS operating mode: „normal mode“ only one PS measurement is performed during one PS repetition time. In PS operating mode „twice mode“ two independent PS measurement are performed within one PS repetition time. Both measurements are independent and can trigger the interrupt. This feature can be used to decrease the interrupt update time if the persistence function (register 0x43h) is used. 2014-07-25 19 Version 1.0 SFH 7779 .

PS and ALS VIS Interrupt status is readable via register 0x4Ah or at the INT pin of the sensor. The Interrupt persistence function is only valid for PS measurements and is defined at register (0x43h). The INT pin of the SFH 7779 is an open drain output and should be pulled-up to VI/O by an external resistor. When VDD is supplied to the sensor the INT pin is per default in high ohmic (inactive) state. The INT status becomes inactive by writing an INT reset command, reading the INT status register or performing a software reset. The INT status stays in its last state when the sensor is set to the standby mode. In the INT active state „low“ the sensor consumes ~25µA extrra current. Therefore OSRAM recommends to set the INT state to high impedance before setting the sensor in standby mode. Below the ALS and PS INT modes are described for the unlatched mode. In latched mode the switching back to the „inactive“ INT state is depending on an interrupt reset or on reading out the INT status register. ALS INT mode: The ALS VIS threshold levels high (register 0x4Fh & 0x50h) and low (register 0x4Fh & 0x50h) are only valid for the ALS VIS measurement values. The ALS VIS INT mode is fixed and can not be adapted via register. The thresholds define a window with the following functionality: ALS INT is active, if the ALS VIS measurement values are outside the window ALS INT is inactive, if the ALS VIS measurement results are inside the window. PS INT Modes: Bit of interrupt function setting register (0x4Ah) 00 PS_TH is active only: The INT state is active, if the PS measurement result is equal or higher than the set PS_TH high 2014-07-25 26 Version 1.0 SFH 7779 threshold. The INT state is inactive, if the PS measurement result is lower than the set PS_TH high threshold. PS INT active PS INT inactive PS signal PS_TH 01 PS_TH & PS_TL (PS high & low threshold) are active as hysteresis: PS_TH and PS_TL are working as a hysteresis. If the PS measurement signal is higher than the PS high threshold (PS_TH) the INT state is switched to active. If the PS measurement signal is lower than the PS low threshold (PS_TL) the INT state is inactive. If once the interrupt signal becomes active, the INT status is kept active until the measurement result becomes less than the PS_TL register value. PS INT active PS INT inactive PS signal PS_TH PS_TL 10 PS_TH & PS_TL (PS high & low threshold) are active as outside detection: In case of “PS outside detection“ mode interrupt signal inactive means that the measurement result is within the registered threshold level and the interrupt signal active means that the meas- 2014-07-25 27 Version 1.0 SFH 7779 urement result is out of registered threshold level.

Cleaning / Washing In general, OSRAM Opto Semiconductors does not recommend a wet cleaning process for the components SFH7779 as the package is not hermetically sealed. Due to the open design, all kind of cleaning liquids can infiltrate the package and cause a degradation or a complete failure of the LED or ASIC. It is also recommended to prevent penetration of organic substances from the environment which could interact with the hot surfaces of the operating chips. Ultrasonic cleaning is generally not recommended for all types of LEDs (see also the application note "Cleaning of LEDs"). As is standard for the electronic industry, OSRAM Opto Semiconductors recommends using low-residue or no-clean solder paste, so that PCB cleaning after soldering is no longer required. In any case, all materials and methods should be tested beforehand in order to determine whether the component will be damaged in the process. 2014-07-25 31 Version 1.0 SFH 7779 Reflow Soldering Profile Preconditioning: JEDEC Level 3 acc. to JEDEC S-STD-020-D OHA04525 300 ˚C T 250 Tp 245 ˚C 240 ˚C tP 217 ˚C 200 tL 150 tS 100 50 25 ˚C 0 0 50 100 150 200 s 300 250 t OHA04612 Profile Feature Profil-Charakteristik Symbol Symbol Pb-Free (SnAgCu) Assembly Minimum Ramp-up rate to preheat*) 25 °C to 150 °C Time tS TSmin to TSmax tS 60 Ramp-up rate to peak*) TSmax to TP Recommendation Maximum 2 3 100 120 2 3 Unit Einheit K/s s K/s Liquidus temperature TL 217 Time above liquidus temperature tL 80 100 s Peak temperature TP 245 260 °C Time within 5 °C of the specified peak temperature TP - 5 K tP 20 30 s 3 6 K/s 10 Ramp-down rate* TP to 100 °C 480 Time 25 °C to TP All temperatures refer to the center of the package, measured on the top of the component * slope calculation DT/Dt: Dt max. 5 s; fulfillment for the whole T-range 2014-07-25 °C 32 s Version 1.0 SFH 7779 Disclaimer Disclaimer Attention please!
