Part Number: BQ33100

Hello,

I want to implement SMBus HAL for BQ33100. I am using host micro which has i2c interface.

what care / consideration I should take while developing the driver in I2C Master.

Dose the IC have any separate features or some changes wrt I2C read write functions?

How to enable/ disable PEC used for communication (as given in Product data sheet : 8.5.1.3)

I came to know there is some change in block read/write operation in SMbis and I2C.

what changes in implementation is required from normal i2c block read/ write??

Hi Mandar,
This app note discusses how to implement SMBus communication via I2C using an MSP430 as an example.

There is also supposed to be source code with it but I cannot find the .zip file containing it at this moment.
Hopefully it helps!
