Measurement time ( integration time ) of H-Resolution Mode is so long that some kind of noise( including in 50Hz / 60Hz noise ) is rejected. And H-Resolution Mode is 1 l x resolution so that it is suitable for darkness ( less than 10 lx ) H-resolution mode2 is also suitable to detect for darkness. ●Explanation of Asynchronous reset and Reset command "0000_0111" 1) Asynchronous reset All registers are reset and BH1751FVI becomes power down during DVI = 'L'. Initial reset is not necessary, because power on reset function is included in this product. 2) Reset command Reset command is for only reset Illuminance data register. ( reset value is '0' )It is not necessary after power supply to VCC because power on reset function is included in this product. It is used for removing previous measurement result. This command is not working in power down mode, so that please set the power on mode before input this command. www.rohm.com © 2010 ROHM Co., Ltd.

(sensor sensitivity adjusting ) BH1751FVI is possible to change sensor sensitivity. And it is possible to cancel the optical window influence (difference with / without optical window) by using this function. Adjust is done by changing measurement time. For example, when transmission rate of optical window is 50% (measurement result becomes 0.5 times if optical window is set ), influence of optical window is ignored by changing sensor sensitivity from default to 2 times Sensor sensitivity is shift by changing the value of MTreg (measurement time regisiter). MTreg value has to set 2 times if target of sensor sensitivity is 2 times. Measurement time is also set 2 times when MTreg value is changed from default to 2 times. ex) Procedure for changing target sensor sensitivity to 2 times. Please change Mtreg from”0100_0101” (default) to”1000_1010” (default * 2). 1) Changing High bit of MTreg ST Slave Address R/W 0 Ack 01000_100 Ack SP 2) Changing Low bit of MTreg ST Slave Address R/W 0 Ack 011_01010 Ack SP 3) Input Measurement Command ST Slave Address R/W 0 Ack 0001_0000 Ack SP * This example is High Resolution mode, but it accepts the other measurement. 4) After about 240ms, measurement result is registered to Data Register. ( High Resolution mode is typically 120ms, but measurement time is set twice. ) The below table is seeing the changable range of MTreg.

All rights reserved. 14/16 2010.02 - Rev.A BH1751FVI Technical Note ●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 power 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 the CMOS IC, it is possible that the internal logic may be unstable and rush current may flow instantaneously. 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. Please mount by Footprint dimensions described in the Jisso Information for WSOF6I. This pad is GND level, therefore there is a possibility that LSI malfunctions and heavy-current is generated. www.rohm.com © 2010 ROHM Co., Ltd.
