Controller Driver. NJU6063 Datasheet
RGB LED Controller Driver with PWM Control
■ GENERAL DESCRIPTION
The NJU6063 is RGBLEDcontroller driver with PWMcontrol.
It contains PWM controller, LED drivers, I2C interface and constant current
driver etc.and can controlRGBLED individually.
NJU6063 can reduce board density because the external parts are
unnecessaryfor it includesconstantcurrentdriver.
Making LED a polychromatic light is possible by the control of the PWM
Also, multiple NJU6063 can be controlled bythemultidevice control.
The NJU6063 is suited for a large number of applications such as cellular
phones, car stereo sets, household appliances, illumination equipment and

■ TERMINAL DISCRIPTION
Data Output terminal 1
The following two kinds of use can be selected by the instruction.
1) Multi device control
Please connect it with terminal RSTb of NJU6063 in the next device.
2) Enable control of external LED driver
It can be use as enable control output terminal using an external LED driver. It outputs “H” level
or “L” level by instruction code.
Data Output terminal 2
It outputs the PWM signal same as LED3 Terminal.
It is used to PWM dimming using an external LED driver.
LED Output terminal (Open drain output)
Output level can be divided into 128 steps by PWM signal. Connecting with the cathode of LED.
Connecting with the cathode of LED.
N.C. Not connect. These terminals are electrically open.
External clock input terminal It is used by external clock. Normally open.
Set of Maximum LED drive current. It should connect a resistance between ISET Terminal and
AVSS Terminal to set a maximum LED current.
Reset terminal - Active “L”. "L" status: Reset state "H" status: Operating state
SCL Serial clock input terminal
SDA Serial data input terminal
VDD Digital power supply
VIN Analog power supply
VSS Digital Ground
