Hi Bhavik,

Yes, the BQ34110 can be used for this type of battery. The default settings for the data flash are set for a Li-Ion battery, so make sure to update all of your parameters for the voltages for your battery and the settings based on your application. The attached spreadsheet should help you to find the right settings. Enter the basic parameters on Sheet1 and Sheet2 will show suggested values to help you get started.

Best regards,

Matt

Hello Matt,

I have referred docs you provided. As mentioned in docs configuration can be updated through bqstudio.

I want to know that is that possible to set configuration for lead acid battery without bqstudio.

Hi Bhavik,

Yes, this is possible. The BQ34110 Technical Reference Manual describes how to write to the data flash to program each of the parameters. However, when configuring the device for a new application for the first time, it will be much easier to use BQStudio because you will be able to easily observe the behavior and collect datalogs to evaluate your settings. Without BQStudio, this is much more challenging.

Best regards,

Matt

Hello Matt,

Thanks for your response.

As mentioned in datasheet & manual for BQ34110, To configure parameters using BQStudio there is requirement of EV2400 module to interface with BQ34110.

Is that possible we can use USBtoI2C (Converter) module instead of EV2400 ?.

Is BQStudio support USBtoI2C module instead of EV2400 ? . As I thought EV2400 also doing USB to I2C conversations.

Thanks

Hi Bhavik,

No, unfortunately the EV2400 module is needed. BQStudio is designed to interface with this tool.

The build files (schematics, layout, firmware) are also available on the EV2400 product folder (http://www.ti.com/tool/EV2400) if you would like to build your own.

Best regards,

Matt
