The PCA9551PW/G from NXP Semiconductors is an 8-bit I2C-bus LED driver that simplifies LED blinking operations in I2C and SMBus applications. Its key feature is an internal oscillator with two programmable blink rates, which significantly reduces bus traffic and frees up the master's timer compared to traditional I/O expanders. This allows the bus master to set up the blink frequency and duty cycle for each output once, and then control them with a single command.
The device provides 8 open-drain outputs, each capable of sinking up to 25 mA, with a package total of 100 mA. Unused outputs can function as General Purpose parallel Input/Output (GPIO) pins. It includes a hardware reset pin and Power-On Reset (POR) for initialization. The PCA9551PW/G supports up to eight devices on the same bus using three hardware address pins.
This LED driver is supplied in a TSSOP16 package suitable for surface mounting. It is RoHS3 compliant and lead-free, with halogen-free technology also available for certain variants.
