NXP PCA9533D01118 LED Dimmer
The PCA9533 is a 4-bit I2C-bus and SMBus LED dimmer optimized for RGB color mixing and backlight applications. It features internal oscillation with programmable blink rates and duty cycles, enabling smooth LED dimming in 256 steps. Capable of driving LEDs up to 25 mA per channel and supporting PWM control for brightness and blinking, the device also offers GPIO expansion for versatile applications. Its power-on reset ensures default off states, and it operates over a supply voltage range of 2.3 V to 5.5 V with an I2C clock frequency up to 400 kHz. Available in TSSOP8 and SO8 packages, it supports hot insertion and exceeds robust ESD protection.
