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.

Color sensor

After power-on, the built-in power-on reset circuit operates to set

all registers to their initial conditions (2.).

1. Power-on

With the initial settings, the product is in sleep mode, waiting for

commands.

2. Power-on reset, initialize

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 prod-

uct automatically enters sleep mode after completing a single mea-

surement. 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.

Proximity sensor

With the initial settings, the proximity sensor is in sleep mode.

Therefore, ﬁrst disable the sleep mode (3.). Next, set the drive cur-

rent, pulse count, pulse cycle, and the like. Then, release the reset

to start measuring (4. 5.). Proximity sensor continues to measure

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

mode.

With the initial settings, the 3-color LED driver is in sleep mode.

Therefore, ﬁrst disable the standby mode (3). Next, set the light

emission pulse width of each color, 1/10 mode, and the like. Then,

release the reset to start measuring (4, 5). 3-color LED drivers con-

tinue to operate until they are set to sleep mode. To end operation,

enable standby mode.

Timing chart

Color sensor (manual mode)

Idd

The color sensor only has a single ADC port. As such, pho-

tometry 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 mea-

surement, 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.

Proximity sensor

I²C

command

In the proximity sensor, the light emission pulse count is de-

signed 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 ꢀs to 240 ꢀs in 16-ꢀs 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.
