PCA9550DP,118 NXP LED Driver | 8-TSSOP | 2-bit I2C, 25mA Output

Product Overview

The PCA9550DP,118 from NXP Semiconductors is a 2-bit I2C-bus LED driver designed for low-power, small-footprint applications. Housed in an 8-pin TSSOP package, it provides two open-drain outputs capable of sinking up to 25 mA each. The device operates from a 2.3 V to 5.5 V supply and features programmable blink rates via an internal oscillator. Its I2C interface supports up to 400 kHz clock frequency, allowing easy integration with microcontrollers and SoCs.
