DESCRIPTION

VCNL4040 integrates a proximi ty sensor (PS), ambient light sensor (ALS), and a high power IRED into one small package. It incorporates ph otodiodes, amplifiers, and analog to digital converting circuits into a single chip by CMOS process. The 16-bit hi gh resolution ALS offers excellent sensing capabilities with sufficient selections to fulfill most applications whether dark or high transparency lens design. High and low in terrupt thresholds can be programmed for both ALS and PS, allowing the component to use a minimal amount of the microcontrollers resources. The proximity sensor features an intelligent cancellation scheme, so that cross talk phenomenon is eliminated effectively. To accelerate the PS response time, smart persistence prevents the misjudgment of proximity sensing but also keeps a fast response time. In active force mode, a single measurement can be re quested, allowing another good approach for more design flexibility to fulfill different kinds of applications with more power saving. The patented Filtron TM technology achieves ambient light spectral sensitivity closest to real human eye response and offers the best background light cancellation capability (including sunlight) without utilizing the microcontrollers’ resources. VCNL4040 provides an excellent temperature compensation capability for keeping output stable under various temperature configurations. ALS and PS functions are easily set via the simple command format of I 2C (SMBus compatible) interface protocol. Operating voltage ranges from 2.5 V to 3.6 V. VCNL4040 is packaged in a lead (Pb)-free 8-pin molding package, which offers the best market-proven reliability quality.

APPLICATION INFORMATION

Pin Connection with the Host VCNL4040 integrates proximity sensor, ambient light Sensor, and IRED all together with I 2C interface. It is very easy for the baseband (CPU) to access PS and ALS output data via I2C interface without extra software algorithms. The hardware schematic is shown in the following diagram. Two additional capacitors in the circuit can be used for the following purposes: (1) the 0.1 μF capacitor near the V DD pin is used for power supply noise rejection, (2) the 2.2 μF capacitor - connected to the anode - is used to prevent the IRED voltage from instantly dropping when the IRED is turned on, and (3) 2.2 k Ω is suitable for the pull up resistor of I 2C except for the 8.2 k Ω applied on the INT pin.

THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENT ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT www.vishay.com/doc?91000 Digital Interface VCNL4040 applies single slave address 0x60 (HEX) of 7-bit addressing following I 2C protocol. As figure 12 shows, VCNL4040’s I2C command format is simple for read and write operations between VCNL4040 and the host. The white sections indicate host activity and the gray sections indicate VCNL4040’s acknowledg ement of the host access activity. Write word and read word protocol is suitable for accessing registers particularly for 16-bit data ALS and 12-bit / 16-bit PS data. Interrupt can be cleared by reading data out from register: INT_Flag. All command codes should follow read word and write word protocols. Fig. 12 - Write Word and Read Word Protocol Function Description VCNL4040 applies a 16-bit high resolution ALS that provides the best ambient light sensing capa bility down to 0.01 lux/step which works well under a low transm ittance lens design (dark lens ). A flexible interrupt functio n of ALS (register: ALS_CONF) is also supported. The INT signal will not be triggered by VCNL4040 if the ALS value is not over high INT threshold window level, or lower than low INT threshold window level of ALS. VCNL4 040 detects different light sources such as fluorescent light, incandescent light, sunlight, and white LED with high accuracy ALS data output after detecting algorithm is implemented. For proximity sensor function, VCNL4040 supports different kinds of mechanical designs to achieve the best proximity detection performance for any color of object with mo re flexibility. The basic PS function settin gs, such as duty ratio, integration time , interrupt, and PS enable / disable, and persistence, are handled by the register: PS_CONF1. Duty ratio controls the PS response time. Integration time represents the durati on of the energy being received. The interrupt is triggered when the PS detection levels over the high threshold level setting (register: PS_THDH) or lower than low threshold (register: PS_THDL). If the interrupt function is enabled, the host can react to the interrupt pin, in stead of polling the PS data registers. The INT flag (register: INT_Flag) indicates the type of interrupt that has been tri ggered, depending on the interrupt settings in the configuration registers. PS persistence (PS_PERS) sets up the PS INT trigger conditions, defining the amount of consecutive hits required before an interrupt event occurs . The intelligent cancellation level can be set on register: PS_CANC to reduce the cross talk phenomenon. VCNL4040 also supports an easy to use proximity detection logic mode, that triggers when the PS high threshold is exceeded and automatically resets the interrupt pin when the proximity reading falls beneath the PS low threshold. This functionality can be set in the register: PS_MS. A smart pe rsistence is provided to be able to pr event false PS interrupt trigger events. Descriptions of each of these parameters are shown in table 1.

THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENT ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT www.vishay.com/doc?91000 Adjustable Sampling Time VCNL4040’s LED driver drives the internal IRED with the “LED CATHODE” pin by a pulsed duty cycle. The IRED on / off duty ratio can be set in register: PS_Duty which is related to th e current consumption and PS resp onse time. The higher the duty ratio, the faster the response time achieved with higher power consumption. For example, PS_Duty = 1/320, peak IRED current = 100 mA, averaged current consumption is 100 mA/320 = 0.3125 mA. Initialization VCNL4040 includes default values for each register. As long as power is on, it is ready to be controlled by host via I 2C bus. Threshold Window Setting

  • ALS Threshold Window Setting (Applying ALS INT) Register: ALS_THDH_L and ALS_THDH_M defines 16-bit ALS hi gh threshold data for LSB by te and MSB byte. Register: ALS_THDL_L and ALS_THDL_M defines 16-bit ALS low threshol d data for LSB byte and MSB byte. As long as ALS INT function is enabled, INT will be triggered once the ALS data exceeds ALS_THDH or goes below ALS_THDL. To easily define the threshold range, multiply the value of the resolution (lux/step) by the threshold level (refer to table 14).
  • A L S P e r s i s t e n c e The ALS INT is triggered once the ALS value is higher or lower than the threshold window. The ALS_PERS (1, 2, 4, 8 times) parameter, sets the amount of consecutive hits needed, in order for an interrupt event to trigger.
  • Programmable PS Threshold VCNL4040 provides both high and low thresholds setting for PS (register: PS_THDL, PS_THDH).
  • P S P e r s i s t e n c e The PS persistence function (PS_PERS, 1, 2, 3, 4) helps to avoid false trigger of the PS INT. It defines the amount of consecutive hits needed in order for a PS interrupt event to be triggered.
  • PS Active Force mode An extreme power saving way to use PS is to apply PS active force (r egister: PS_CONF3 command: PS_AF = 1) mode. Anytime host would like to request one proximity measurement, write a ‘1’ into register: PS_CONF3 command: PS_Trig. This triggers a single PS measurement, which can be read from the PS result registers. V CNL4040 stays in standby mode constantly. Data Access All of VCNL4040 16 bit command registers are readable. The result data for ALS, white, and PS measurements can be read out form their respective registers. Each result is made of 2 bytes. Intelligent Cancellation VCNL4040 provides an intelligent cancellation method to reduce cross talk phenomenon for the proximity sensor. The output data will be subtracted by the value set in register: PS_CANC.

THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENT ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT www.vishay.com/doc?91000 Interruption (INT) The VCNL4040 has an interrupt feature for both the PS and ALS channel. The purpose of the interrupt feature is to actively inform the host once INT has been triggered. When the interrupt is enabled, the host does not need to continuously read the data registers of the sensor, but instead can simply react to the interrupt pin. As long as the host enables ALS interrupt (register: ALS_INT_EN) or PS interrupt (register: PS_INT) function, the level of INT pin (pin 6) is pulled low once an interrupt event has been triggered. All registers are accessible even if INT is triggered. ALS INT is triggered when ALS value cr osses over the value set in register: ALS_THDH or below the value set by register: ALS_THDL. PS INT is triggered when the PS value crosses over the value set in register: PS_THDH or falls below the value set in register: PS_THDL. Which of these thresholds to react to, can be set by the PS_INT bits in the register: PS_CONF2. Interruption Flag Register: INT_Flag represents all of the inte rrupt trigger statuses for ALS and PS. If any of these flags trigger from “0” to “ 1”, the INT pin will be pulled low. Once the host reads INT_Flag register, all the flags are cleared (reset to "0"), and the INT pi n is reset to high. PROXIMITY DETECTION LOGIC OUTPUT MODE VCNL4040 has a proximity detection logic mode, enabling the host to read the state of PS (near or far) simply by monitoring the INT pin (pin 6). When this mode is selected, the INT pin is pulled low when an object is close to the sensor (value is above high threshold) and is reset to high when the object moves away (value is below low threshold). Register: PS_THDH / PS_THDL define where these threshold levels are set. It should be noted that whenever the pro ximity detection logic mode has been enab led, the INT pin only reacts to proximity interrupt events. If the host would like to use ALS INT function, the bit PS_MS in the register: PS_MS needs to be set to normal operation mode (PS_MS = 0). In order for the proximity detection logic mode to func tion, one of the PS_INT bits in register: PS_CONF2 must be enabled (“trigger when cl ose”, “trigger when away”, or “trigger wh en close or away”). If PS_INT is set to “INT Disable” the proximity detection logic mode will not function. PROXIMITY DETECTION HYSTERESIS A hysteresis is created by setting the low and high threshold values. With proximity detection logic mode disabled, an interrupt event will trigger and stay triggered until it is cleared in the INT_Flag register. The register is cleared automatically once it is read. If the interrupt flags are not cleared after an interrupt event has occurred, the VCNL4040 will not react to another interrupt event until the INT-Flag register has been cleared. An example of this could be when turning on and off a backlight of a mobile display. First the PS INT triggers when the PS value is over PS_THDH. Th e host switches off the panel backlight and then clears INT. When PS value is less than PS_THDL, host switches on panel backlight.
