PCA9632 vs PCA9633

[Ludità]

Messr NXP,

can you confirm that the products PCA9633DP2 and PCA9632DP2Z are perfectly interchangeable in existing boards without any FW intervention?

Hi Team,

I am using the PCA9632DP2Z to drive a 12V RGB LED. Since this IC operates at 5V, I have incorporated a transistor driver circuit. Kindly review the circuit below and share your feedback or suggestions

Hello Luigi,

Both devices support I2C communication with Fast-mode Plus (1 MHz) and share the same register structures with default settings. The slave address is also identical. So, I believe that no FW changes are necessary. 

BRs, Tomas
