TCA6507 I2C LED Drivers Texas Instruments TCA6507 I2C LED Drivers can automatically gradually fade and control the brightness and blinking pattern while simultaneously using pulse-width modulation intensity control. The device features an internal self-contained oscillator that controls two PWM modules and provides two independent blink/fade patterns. The driver has a very low power consumption of 25uA in operating mode and 10uA in standby, as well as superior drive capability. Applications include consumer, server, computing, and industrial markets, as well as applications in the handset market.
