Products Detail

The PCA9551 is an 8-bit I2C-bus LED driver with programmable blink rates, designed for I2C-bus and SMBus applications to limit bus traffic and free up the master's timer. It features an internal oscillator with two programmable blink rates (0.148Hz to 38Hz), 8 open-drain outputs (25mA per bit, 100mA per package), GPIO expansion capability, internal power-on reset, noise filter on SCL/SDA, active-low reset, and supports hot insertion. Operating voltage range is 2.3V to 5.5V with clock frequency up to 400kHz. Packages include SO16, TSSOP16, and HVQFN16.
