Product details

Description

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.

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 as regular GPIOs.
Internal oscillator requires no external components.
I2C interface logic compatible with SMBus.
Internal power-on reset.
Noise filter on SCL/SDA.
