BQ34110: WIFI I2C Protocol

VINIT GANDHI
Prodigy 20 points
Part Number: BQ34110

Hi - 

apologies incase my question doesn't sound right. this will be first project for me dealing with power electronics and we are yet to hire a consultancy firm to help us design pcb.

basically we have finalize to use TI bq34110 IC to monitor voltage, current , SOH of lead acid batteries. IC supports I2C interface. he circuit will be drawing power from the 12v batteries. 

I do understand IC wil not work without its power, microcontroller, communication component, etc. Somebody wil have to design these component around TI IC to complete the design. I was wondering is there any off the shelves product/micro controller which readily integrates well with TI bq34110. I am aware of Evaluation board but I am assuming it for testing not for production .

also can I integrate TI bq34110 with Advantech IOT Sensors Node like Wise 1520 (link below)? I prefer wise 1520 reads data over i2c adapter and upload it on our server,. Server will take care of all further processes. 

it will be very helpful to me if there is guide on how to build basic essential circuit around the Chip. 

Advantech Wise 1520

    Hi Vinit,

    There are many microcontrollers that can work with the bq34110 for this type of application. For example, I am currently planning to use an MSP430 for a reference design and I have seen many customers using an ARM Cortex based controllers. The controller just needs an I2C interface and a few pins to interface with the ALERT pins of the bq34110 and the LEN pin if desired. The Wise 1520 looks like it should work, but ultimately you need to select the controller based on your system-level needs. I noticed it does have pretty high power consumption, so if it will be using the battery power, you should take that into consideration.

    There are many things to consider when designing this type of system. Always keep safety in mind when working with battery systems.

    Best regards,
    Matt
