BU27006MUC-Z
General Description
BU27006MUC-Z is a digital color sensor IC with Flicker
sensing function. This IC senses Red, Green, Blue
(RGB) and Infrared and converts them to digital values.
The high sensitivity, wide dynamic range and excellent
Ircut characteristics make it possible for this IC to obtain
the accurate illuminance and color temperature of
ambient light. It is also possible to detect flicker light
noise of display and room lighting. It is ideal for adjusting
LCD backlight of TV, mobile phone and tablet PC.
Features
RGB/IR + Flicker Detection
Built-in Ircut Filter
Rejecting 50 Hz/60 Hz Light Noise for Color Sensor
I2C Bus Interface (f/s mode support)
Correspond to 1.8 V Logic Interface
LUX Resolution 0.015 lx/count (Typ) in Color Sensor
(In the highest gain and the longest measurement time
setting)
Sampling frequency 1 kHz/2 kHz is selectable in flicker
sensor

(Note 1) If there is a device falls sharply among other devices connected to the SDA, SCL, and INT pins, it might generate undershoot and the pin voltage might
be the ground potential or below. When the undershoot occurs, must take a measure like adding a capacitor near to the pin of the device concerned.
(Note 2) Dispose a bypass capacitor as close as possible to the IC
(Note 3) Please use the NC pin as open pin

Caution 1: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit
between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is
operated over the absolute maximum ratings.
Caution 2: Should by any chance the maximum junction temperature rating be exceeded the rise in temperature of the chip may result in deterioration of the
properties of the chip. In case of exceeding this absolute maximum rating, design a PCB with thermal resistance taken into consideration by
increasing board size and copper area so as not to exceed the maximum junction temperature rating.
