The PCA9550DP,118 from NXP Semiconductors is an LED driver designed for I2C-bus and SMBus applications. It features two LED drivers with programmable blink rates, allowing for efficient control of LEDs while minimizing bus traffic and freeing up the I2C master.
Key specifications include an operating supply voltage range of 2.3 V to 5.5 V and a clock frequency up to 400 kHz. Each open-drain output can directly drive LEDs with a sink current of up to 25 mA per bit and 50 mA per package. The device offers two selectable, fully programmable blink rates, ranging from 0.172 Hz to 44 Hz, with adjustable frequency and duty cycle.
Unused I/O bits can function as general-purpose parallel input/output (GPIO) expansion. The PCA9550DP,118 includes an internal oscillator, eliminating the need for external components, and features an active-low hardware reset pin and power-on reset. It is supplied in an 8-TSSOP package suitable for surface mounting.
This LED driver is ideal for applications where precise LED blinking control is required without constant master intervention, such as status indicators or notification lights in embedded systems.
