Color/proximity sensor
P12347-01CT
Color sensor, proximity sensor, and 3-color LED
incorporated into a single package
This is a multifunctional sensor that incorporates a color sensor, proximity sensor, and 3-color LED in a small package (5.5 ×
1.7 × 1.0 mm). It can be used to adjust the display image quality, perform touchscreen on/off control, indicate incoming calls,
and so forth on smartphones and the like. The color sensor not only detects the RGB ratios of ambient light but also functions
as an illuminance sensor. This feature enables image quality to be adjusted in fine detail. In smartphone applications, the
proximity sensor detects when a face draws near and turns off the touchscreen function and the LCD backlight. We provide an
evaluation kit for this product as well as an evaluation board. Contact us for detailed information.

*1: When there is a temperature difference between a product and the surrounding area in high humidity environment, dew condensation
may occur on the product surface. Dew condensation on the product may cause deterioration in characteristics and reliability.
*2: When driven externally
*3: Duty ratio ≤ 10%, pulse width ≤ 0.1 ms
*4: Moisture absorption and reflow conditions: JEDEC J-STD-020D LEVEL3
Note: Exceeding the absolute maximum ratings even momentarily may cause a drop in product quality. Always be sure to use the
product within the absolute maximum ratings.

*8: Set the threshold level to 0x10 (10000 in binary notation) or higher.
*9: With the initial setting, the 3-color LED emits pulses. When set to DC mode, it emits DC light.
Note: When using the LED in DC mode, set the current for red to 30 mA or less and that for green and blue to 20 mA or less.
If the LED forward current is set to a high level, the LED will illuminate brightly. Be careful as the bright light may be hazardous
to the eyes if viewed directly.

After power-on, the built-in power-on reset circuit operates to set
all registers to their initial conditions (2.).
With the initial settings, the product is in sleep mode, waiting for
commands.
To set measurement conditions, enter commands via the I2C bus.
This product starts measuring when ADC reset changes from 1 to 0.
Therefore, to write to registers, ADC reset must be set to 1 (3.).
After setting measurement conditions (4.), release ADC reset to
start measuring (5.). There are two operation modes: fixed time
mode and manual setting mode. In manual setting mode, the product automatically enters sleep mode after completing a single measurement. In fixed time mode, the product repeats measurement
and data storage. During this repetition, if ADC reset or Color sleep
is set to 1 with an I2C command, the product stops its operation.

until it is set to sleep mode. To end measurement, enable sleep

Integration
time
(sum of the integration times of each color)
The color sensor only has a single ADC port. As such, photometry is performed consecutively for each color. The data
of each color is stored temporarily in buffer registers (not
the I2C register). After the completion of the infrared measurement, the entire set of data is stored in the I2C register.
If this product is set to manual mode, after the integration
time elapses, it will automatically switch to sleep mode. The
integration time per cycle is the sum of the detection time
of each color.

In the proximity sensor, the light emission pulse count is designed to be adjustable in integer multiples of 3 from 3 to 45
in order to increase measurement precision. The interrupt
signal (INT) is set to 1 only when all pulses are detected.
A red LED is used for light emission. The drive current can
be changed in the range of 8 mA to 96 mA in 8-mA steps.
The proximity cycle can be changed in the range of 65.5 ms
to 982.5 ms in 65.5-ms steps. Measurement is performed
every proximity cycle. When measurement is not performed,
the sensor automatically switches to sleep mode.

The 3-color LED emits light in the order red, green, and
blue. The light emission pulse width can be set in the range
of 0 μs to 240 μs in 16-μs steps (16 levels total). The light
emission pulse width can be set for each color. The light
emission cycle is fixed at approximately 1.6 ms, and the
drive current is fixed at 8 mA.
If set to low current mode, the forward current of each color
LED is set to 0.8 mA, which is 1/10 the initial setting. If set
to DC mode, the drive current is set to direct current and
can be set in the range of 8 mA to 120 mA in 8-mA steps.
In DC mode, set the forward current to 30 mA or less for
red and 20 mA or less for green and blue.
