Product Summary
The TCA6507PWR is a low-voltage 7-bit I2C and SMBus LED driver with intensity control and shutdown. The TCA6507PWR is designed to control (or dim) LEDs via the I2C interface. Without this device, the microprocessor or microcontroller must be actively involved in turning on and off the LEDs (per the required dimming rate), which uses valuable processor time and the overloads I2C bus. The TCA6507PWR alleviates this issue by limiting the number of operations required by the processor in blinking LEDs and, thus, helps to create a more efficient system.
