Product Overview


The TCA6507PW is a low-voltage 7-bit I²C and SMBus LED Driver with intensity control and shutdown. Designed to control LEDs via the I²C interface (serial clock (SCL), serial data (SDA)). 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 TCA6507 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. This device can be used for driving LEDs and for general-purpose parallel output expansion. The TCA6507 has three select registers, which can be used to configure each LED output into one of seven different operating modes. At power on, the outputs are in high impedance.
  • Open-drain outputs directly drive LEDs
  • Can be configured into two independent banks of LED drivers
  • LED intensity set using pulse width modulation
  • 6 Steps of maximum intensity control from fully-off to fully-on states
  • Schmitt-trigger action allows slow input transition & better switching noise immunity at inputs
  • Internal power-on reset
  • Internal oscillator requires no external components
  • Green product and no Sb/Br
