PCA9531PW,118 NXP LED Driver | 16-TSSOP | I2C, 8-bit PWM

Product Overview

The PCA9531PW,118 from NXP Semiconductors is a 8-bit I2C-bus LED driver with programmable blink rates and PWM dimming. Housed in a compact 16-TSSOP package, it is designed to control up to 8 individual LEDs or groups of LEDs with minimal microcontroller overhead. The device features an internal oscillator, allowing standalone blinking without continuous I2C communication. It operates from a 2.3V to 5.5V supply and supports up to 25mA output current per channel.
