Product Number: LTC6803-3
Hi,
I'm using a stm32l452ret to communicate directly with the LTC6803 and LTC3300 without an SPI Isolator. Unfortunately, I have yet to have a response from either chip when sending them simple commands like reading config registers on startup for the ltc6803-3 and reading the balance state for the ltc3300. All i'm trying to do is detect of the chips are able to respond before attempting further communication. Is an isolator between the microcontroller and ics necessary? Is it meant to be fine as long as I have both grounds tied together?
Thanks for your help in advance.
