TCA6507 Datasheet (Texas Instruments) - Low-Voltage 7-Bit I2C and SMBus LED Driver

TCA6507, Low-Voltage 7-Bit I2C and SMBus LED Driver

This 7-bit LED dimmer for the two-line bidirectional bus (I2C) is designed to control (or dim) LEDs through the I2C interface.

Without this device, the microcontroller must be actively involved in turning on and off the LEDs (per the required dimming rate), which uses valuable processor time.
