PCA9531 Datasheet - NXP

PCA9531 8-bit I2C LED dimmer

The PCA9531 is an 8-bit I2C & SMBus I/O expander optimized for dimming LEDs in 256 discrete steps for Red/Green/Blue (RGB) color mixing and back light applications. The PCA9531 contains an internal oscillator with two user programmable blink rates and duty cycles coupled to the output PWM. The LED b.

PCA9531 Features

* Eight LED drivers (on, off, flashing at a programmable rate)

* Two selectable, fully programmable blink rates (frequency and duty cycle) between 0.625 and 160 Hz (1.6 and 6.25 milliseconds)

* 256 brightness steps

* Input/outputs not used as LED drivers can be used
