New Japan Radio NJU6062
NJU6062
Full Color LED Controller Driver with PWM Control
GENERAL DESCRIPTION
The NJU6062 is a full color LED controller driver. It can
control and drive a 3 in 1 packaged (Red, Green and
Blue) LED.
The NJU6062 contains PWM luminance (Pulse Width
Modulation) control circuit , LED driving circuit, MPU
interface.
The PWM signal control the duty cycle of each RGB
LED delicately, therefore can recognize a lot of colors.
Enable terminal (ON/OFF) is possible to synchronize
with a sound source..
It requires only four external components such as three
resistors for LED current adjustment, which enables the
NJU6062 to save PCB space.
Multi Device control is enabled and it is possible to
control the multiple NJU6062 by a I2C address.
The NJU6062 is suitable for cellular phone, car audio
and so on.
