DESCRIPTION

VCNL3036 integrates a biosensor (BIO), a mux, and a driver for up to 3 external IREDs / LEDs into one small package. It incorporates photodiodes, amplifiers, and analog to digital converting circuits into a single chip by CMOS process. BIO programmable interrupt features of individual high and low thresholds offers the best utilization of resource and power saving on the microcontroller. The biosensor features an intelligent cancellation scheme, so that cross talk phenomenon is eliminated effectively. To accelerate the BIO response time, smart persistence prevents the misjudgment of proximity sensing but also keeps a fast response time. Active force mode, one time trigger by one instruction, is another good approach for more design flexibility to fulfill different kinds of applications with more power saving. VCNL3036 provides an excellent temperature compensation capability for keeping output stable under various temperature configurations. BIO functions are easily operated via the simple command format of I 2C (SMBus compatible) interface protocol. Operating voltage ranges from 2.5 V to 3.6 V. VCNL3036 is packaged in a lead (Pb)-free 8-pin QFN pack age, which offers the best market-proven reliability quality.

All operations can be controlled by the command register. The simple command structure helps us ers easily program the operation setting and latch the light data from VCNL3036. As Fig. 10 shows, VCNL3036’s I 2C command format is simple for read and write operations between VCNL3036 and the host. The white sections indicate host activity and the gray sections indicate VCNL3036’s acknowledgement of the host access activity. Write word and read word protocol is suitable for accessing registers particularly for 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.

THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENT ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT www.vishay.com/doc?91000 Function Description For proximity sensor function, VCNL3036 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 duration of the energy being received. The interrupt is asserted 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 reads the PS output data from VCNL3036 that saves host loading from periodically reading PS data. More than that, INT flag (register: INT_Flag) indicate s the behavior of INT triggere d under different conditions. PS persistence (PS_PERS) sets up the PS INT asserted conditions as long as the PS output value continually exceeds the threshold level. The intelligent cancellation level can be set on register: PS_CANC to reduce the cross talk phenomenon. VCNL3036 also supports an easy use of proximity detection logic output mode that outputs just high / low levels saving loading from the host. Normal operation mode or proximity detection l ogic output mode can be selected on the register: PS_MS. A smart persistence is provided to get faster PS response time and prevent false trigger for PS. Descriptions of each slave address operation are shown in table 1. Note

THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENT ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT www.vishay.com/doc?91000 Adjustable Sampling Time VCNL3036’s embedded LED driver drives up to 3 external LEDs by a pulsed duty cycle. The LED on / off duty ratio is programmable by I 2C command at register: PS_Duty which is related to the current consumption and PS response time. The higher the duty ratio adopted, the faster response ti me achieved with higher power consumption. For example, PS_Duty = 1/320, peak LED current = 100 mA, averaged current consumption is 100 mA/320 = 0.3125 mA. Initialization VCNL3036 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

  • Programmable PS Threshold VCNL3036 provides both high and low thresholds 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 tr igger of the PS INT. For example, if PS_PERS = 3 times, the PS INT will not be asserted unless the PS value is greate r than the PS threshold (PS_THDH) value for three periods of time continuously
  • PS Active Force Mode An extreme power saving way to use PS is to apply PS active force (register: PS_CONF3 command: PS_FOR = 1) mode. Anytime host would like to read out just one of PS data, write in ‘1’ at register: PS_CONF3 command: PS_FOR_Trig. Without commands placed, there is no PS data output. VCNL3036 stays in standby mode constantly Intelligent Cancellation VCNL3036 provides an intelligent cancellation method to reduce cross talk phenomenon for the proximity sensor. The output data will be subtracted by the input value on 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) VCNL3036 has PS interrupt feature operated by a single pin “INT”. The purpose of the interrupt feature is to actively inform the host once INT has been asserted. With the interrupt function applied, the host does not need to be constantly pulling data from the sensor, but to read data from the sens or while receiving interrupt request from the sensor. As long as the host enables PS interrupt (register: PS_INT) function, the level of INT pin (pin 7) is pulled low once INT asserted. All registers are accessible even if INT is asserted. To effectively adopt PS INT function, it is recommended to use PS detection mechanism at register: PS_INTT = 1 for the best PS detection performance wh ich can be adjusted by high / low THD level of PS. PS INT trigger way is defined by register: PS_INT. Interruption Flag Register: INT_Flag represents all of interrupt trigger status for PS. Any flag value changes from “0” to “1” state, the level of INT pin will be pulled low. As long as host reads INT_Flag data, the bit will change from “1” state to “0” state after reading out, the INT level will be returned to high afterwards. PROXIMITY DETECTION LOGIC OUTPUT MODE VCNL3036 provides a proximity detection logic output mode that uses INT pin (pin 7) as a proximity detection logic high / low output (register: PS_MS). When this mode is selected, the PS output (pin 7; INT/Pout) is pulled low when an object is closing to be detected and returned to level high when the object moves away. Register: PS_THDH / PS_THDL defines how sensitive PS detection is. One thing to be stated is that whenever proximity detection logic mode applied, INT pin is only used as a logic high / low output. Meanwhile, host has to simulate the GPIO pin as an INT pin function. If not, host needs to periodically reading the state of INT at this GPIO pin. PROXIMITY DETECTION HYSTERESIS A PS detection hysteresis is important that keeps PS state in a certain range of detection distance. For example, PS INT asserts when PS value over PS_THDH. Host switches off panel backlight and then clears INT. When PS value is less than PS_THDL, host switches on panel backlight. Any PS value lower than PS_THDH or higher than PS_THDL, PS INT will not be asserted. Host does keep the same state. MULTIPLEX FEATURE WITH VCNL3036 VCNL3036 allows to connect up to 3 external LEDs. Each may be selected separate to allow for normal proximity. If one select e.g. LED2 then also PS2 delivers the corresponding proximity data. To allow for a fast quasi-parallel measurements of all three channels the MPX_MODE may be activated (set to “1”). Within “PS_FORCE_MODE” all three LEDs will be sequentially switched and available pro ximity result of this directly shown within the three PS_DATA register. Beside MPX_MODE enabled and PS_FORCE_MODE set this sequence starts direct afte r setting the PS_TRIG bit. Availability of the data will be indicated with setting the MPX_DATA_READY flag or also the Interrupt if this is set-up also. Please see below diagram.

The value of the pull-up resistor at the INT line could be 10 kΩ applied on the INT pin. Fig. 10 - Circuitry with just One Common Power Supply Source For high currents of the LEDs and / or powe r supply close to the lower limit of 2.5 V this R-C decoupling will prevent that the VDD voltage drop below specified minimum. LEDs / IREDs between 550 nm (green) and 950 nm (IR) fit to the sensitivity of the proximity photodiode. Mechanical placement of the external IRED depends on the application.
