PCA9551D,118 NXP LED Driver | 16-SO | I2C, 8-bit PWM

Product Overview

The PCA9551D,118 from NXP Semiconductors is a 8-bit I2C-bus LED driver with programmable blink rates and PWM dimming control. Housed in a compact 16-SO 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 simple, low-pin-count LED control.
