The reference is as follows. Illuminance detection range [lx] ~1,000 ~10,000 ~100,000 Gain Mode H-Gain Mode M-Gain Mode L-Gain Mode This device will be mounted under the optical window in actual designing. Therefore, there is a possibility that the illuminace to ALS( Ambient Light Sensor) will be less than the illuminance on the final product surface. Please consider the attenuation of light through the optical window. Please set output resistance value( R1) within the range of 1 kΩ ~1MΩ which needs to be smaller than the input impedance of the next circuit. 2) Approximate formula of IOUT output voltage in each Gain Mode (1) H-Gain mode The output voltage is calculated as below. -6 Viout= 0.6 x 10 x Ev x R1 Viout is IOUT output voltage [V]. Ev is an illuminance of the ALS surface [lx]. R1 is IOUT output resistor[Ω]. (For example) In case you want to convert the illuminance value up to 500 lx by ADC. If the maximum voltage of ADC input is 2V, output resistor value will be as below. -6 R1 = Viout/(0.6 x 10 x Ev) -6 = 2 /(0.6 x 10 x 500) = 6667[Ω] ⇒6.8[kΩ] (2) M-Gain mode The output voltage is calculated as follows. -6 Viout= 0.06 x 10 x Ev x R1 (3) L-Gain mode The output voltage is calculated as follows. -6 Viout= 0.006 x 10 x Ev x R1 3) C1 (1) To reject the flicker light.. In case IOUT output is R1 only and an ALS receives the artificial lights such as fluorescent lamps and incandescent lamps synchronized with 50/60 Hz of AC power supplies, the output current has a ripple. If you want to reject this ripple, please add C1 to R1 in parallel. Please set it to C1 x R1 = about 0.1 as a time constant. (2) To control backlight smoothly by using illuminance value. C1 is effective to control backlight smoothly for a rapid changing of the illuminance. In this case, please set it to C1 x R1 = about 1 ~ 10 as a time constant. It is not necessary if you average illuminance value with software to change backlight smoothly. Please note that the rise time becomes slow at power-on and recovery from shutdown mode to operation mode. www.rohm.com © 2012 ROHM Co., Ltd.

All rights reserved. 6/8 2012.02 - Rev.D Technical Note BH1603FVC ●Notes for use 1) Absolute Maximum Ratings An excess in the absolute maximum ratings, such as supply voltage ( Vmax ), temperature range of operating conditions (Topr), etc., can break down devices, thus making impossible to identify breaking mode such as a short circuit or an open circuit. If any special mode exceeding the absolute maximum ratings is assumed, consideration should be given to take physical safety measures including the use of fuses, etc. 2) GND voltage Make setting of the potential of the GND terminal so that it will be maintained at the minimum in any operating state. Furthermore, check to be sure no terminals are at a potential lower than the GND voltage including an actual electric transient. 3) Short circuit between terminals and erroneous mounting In order to mount ICs on a set PCB, pay thorough attention to the direction and offset of the ICs. Erroneous mounting can break down the ICs. Furthermore, if a short circuit occurs due to foreign matters entering between terminals or between the terminal and the power supply or the GND terminal, the ICs can break down. 4) Operation in strong electromagnetic field Be noted that using ICs in the strong electromagnetic field can malfunction them. 5) Inspection with set PCB On the inspection with the set PCB, if a capacitor is connected to a low-impedance IC terminal, the IC can suffer stress. Therefore, be sure to discharge from the set PCB by each process. Furthermore, in order to mount or dismount the set PCB to/from the jig for the inspection process, be sure to turn OFF the power supply and then mount the set PCB to the jig. After the completion of the inspection, be sure to turn OFF the power supply and then dismount it from the jig. In addition, for protection against static electricity, establish a ground for the assembly process and pay thorough attention to the transportation and the storage of the set PCB. 6) Input terminals In terms of the construction of IC, parasitic elements are inevitably formed in relation to potential. The operation of the parasitic element can cause interference with circuit operation, thus resulting in a malfunction and then breakdown of the input terminal. Therefore, pay thorough attention not to handle the input terminals; such as to apply to the input terminals a voltage lower than the GND respectively, so that any parasitic element will operate. Furthermore, do not apply a voltage to the input terminals when no power supply voltage is applied to the IC. In addition, even if the power supply voltage is applied, apply to the input terminals a voltage lower than the power supply voltage or within the guaranteed value of electrical characteristics. 7) Thermal design Perform thermal design in which there are adequate margins by taking into account the permissible dissipation (pd) in actual states of use. 8) Treatment of package Dusts or scratch on the photo detector may affect the optical characteristics. Please handle it with care. 9) Rush current When power is first supplied to this IC, rush current may flow instantaneously. Because it is possible that the charge current to the parasitic capacitance of internal photo diode or the internal logic may be unstable. Therefore, give special consideration to power coupling capacitance, power wiring, width of GND wiring, and routing of connections. 10) The exposed central pad on the back side of the package There is an exposed central pad on the back side of the package. But please do it non connection. ( Don't solder, and don't do electrical connection ) Please mount by Footprint dimensions described in the Jisso Information for WSOF6. This pad is GND level, therefore there is a possibility that LSI malfunctions and heavy-current is generated. www.rohm.com © 2012 ROHM Co., Ltd.
