PCA9551PW,118 NXP LED Driver | 16-TSSOP | I2C, 8-bit PWM

Product Overview

The PCA9551PW,118 from NXP Semiconductors is an 8-bit I2C-bus LED driver with programmable blink rates and PWM dimming control. Housed in a compact 16-TSSOP package, it is designed for efficient control of up to 8 individual LEDs or groups. The device features an internal oscillator with two programmable blink frequencies and duty cycles, enabling smooth brightness control without microcontroller intervention. Its I2C interface supports up to 400 kHz bus speed, and the device can be configured for either push-pull or open-drain outputs. Operating from 2.3V to 5.5V, it is suitable for a wide range of low-power applications.
