The PCA9551PW,118 from NXP Semiconductors is an 8-bit I2C-bus LED driver designed for applications requiring blinking LEDs while minimizing bus traffic. This device features an internal oscillator with two programmable blink rates, allowing for flexible control of LED flashing frequency and duty cycle between 0.148 Hz and 38 Hz.
With 8 open-drain outputs capable of directly driving LEDs up to 25 mA per bit, and a total package sink current of 100 mA, the PCA9551PW,118 is suitable for various LED driving tasks. Outputs not used for LED control can function as general-purpose parallel I/O (GPIO).
The device operates over a supply voltage range of 2.3 V to 5.5 V and supports I2C-bus and SMBus interfaces up to 400 kHz. It includes features like power-on reset, an active-low hardware reset pin, and noise filters on SCL/SDA inputs. The PCA9551PW,118 is available in a 16-TSSOP package, suitable for surface mounting.
This LED driver is ideal for applications where the MCU needs to be freed from constant LED on/off commands, such as status indicators, notification lights, or simple display elements in embedded systems.
