PCA9533 Features

* 4 LED drivers (on, off, flashing at a programmable rate)
* 2 selectable, fully programmable blink rates (frequency and duty cycle) between 0.591 Hz and 152 Hz (1.69 seconds and 6.58 milliseconds)
* 256 brightness steps
* Input/outputs not used as LED drivers can b

PCA9533 Applications

* The PCA9533 contains an internal oscillator with two user programmable blink rates and duty cycles coupled to the output PWM. The LED brightness is controlled by setting the blink rate high enough (> 100 Hz) that the blinking cannot be seen and then using 2004 Oct 01 2 Philips Semiconductors Pr
