The PCA9551 LED Blinker from Philips Semiconductors blinks LEDs in I2C and SMBus applications where it is necessary to limit bus traffic or free up the I2C master's (MCU, MPU, DSP, chipset, etc.) timer. The uniqueness of this device is the internal oscillator with two programmable blink rates. To blink LEDs using conventional I/O expanders, the bus master must send repeated commands to the LEDs, increasing the amount I2C bus traffic and using up a timer. The PCA9551 instead requires only the initial set up command to program Blink RATE 1 and Blink RATE 2 (ie, the frequency and duty cycle) for each individual output. From then on, only one command is required to turn each individual open drain output ON, OFF, or to cycle at RATE 1/2. Maximum output sink current is 25 mA per bit and 100 mA per package. The LED Blinker can also be used to dim LEDs by varying duty cycle. Packages: SO16, TSSOP16.
