PCA9552BS,118 NXP LED Driver | 24-HVQFN (4x4) | 8-bit I2C, PWM

Product Overview

The PCA9552BS,118 from NXP Semiconductors is a 8-bit I2C-bus LED driver with programmable blink rates and PWM dimming. Housed in a compact 24-HVQFN (4x4 mm) package, it is designed for efficient control of up to 8 individual LEDs or groups. The device operates from a 2.3V to 5.5V supply and features an open-drain output structure capable of sinking up to 25 mA per channel. Its I2C interface supports standard (100 kHz) and fast-mode (400 kHz) communication, making it ideal for applications requiring precise LED brightness control and minimal board space.
