Question 5: I’m using LEDs with integrated Zener diodes and the IC is getting very hot.
Why?

The IC outputs can be set to either open-drain or push-pull and default to push-pull
outputs. In this application with the Zener diodes, they need to be set to open-drain
since in the push-pull architecture there is a low resistance path to ground through the
Zener and this is causing the IC to overheat. The PCA9632/33/34/35 ICs all power-up
in the push-pull output mode and with the logic state HIGH, so one of the first things
that need to be done is to set the outputs to open-drain.
