PCA9450 without using I2C interface

Bata · ‎07-20-2023

Is it possible to operate the PCA9450 without using I2C?

If possible, please let me know the pin setting when not using I2C.
(e.g. SDAx and SCLx to GND, etc.)

Also, are there any restrictions other than the default settings due to not using I2C?

Dear Kawabata-san,

If there is no need to reconfigure and monitor the status of the device during the operation, it is possible to operate it without I2C, there is no periodic watchdog required etc. like in other PMICs.

Having said that, we do not recommend this type of operation, even if there is no need to modify the default settings, having the ability to read the fault statutes etc. is often required and useful.

Best regards,

Tomas
