Part Number: BQ25120A

Hi,

I'm looking to control BQ25120A from NRF52832. Is there a reference code that I can leverage for my development?

hi Tajinder,

the BQ25120A is a relatively simple device that should be up and running if you have simple I2C communication. You could also use it in standalone mode where no communication is required as well.

I have attached some sample C code (below link)for the BQ25120A but I would probably start with the EVM and EV2400 to familiarize with the initial development and registers.

Thanks Gautam, the sample C code is quite useful. You mentioned that device could also be used in standalone without i2c communication. I've a follow on question:

I can see two state machines in the datasheet. Are those HW state machines?

If I initialise the HW with all the required settings, will state machine take care of the transitions itself? I was thinking of only monitoring the fault using INT pin and clear them as required.

Tajinder,

that is correct. the device will take care of the transitions.
