New Japan Radio Production PWM type 3 color LED control driver

Nippon wireless (New Japan Radio) to complete the development of PWM control type 3 color LED --NJU6062 drive and start input output. The product is suitable for mobile phones, car audio and other decorative lights LED control.

NJU6062LED IC driver control, PWM dimming control circuit is composed of (LED1 (R) /LED2 (G) /LED3 (B) /LED4 4 channel), LED controller, I2C interface circuit, the brightness can be adjusted separately 3 color LED, multi component control function. NJU6062 through the I2C interface control, help to minimize the CPU common port. At the same time, the product supports "multi component control" function, through a I2C bit to control multiple NJU6062.

NJU6062 PWM dimming control circuit with 256 bit resolution, can control 16 million color (R:256step * G:256step * B:256step) light, also can through the LED4 PWM directive will be converted to DATAOUT signal output, as the external peripheral circuit (the brightness of background light regulation, Ma Dakong system) control signal.

This product uses FFP12 small package (2.0x2.0x0.85mm), suitable for portable devices. Japan has begun to supply samples of wireless NJU6062 in February 2008, started production in May 2008, put into operation after the scheduled 200 thousand per month.
