Part Number: BQ34110

Tool/software:

We have made the schematic for BQ34110

Our specs:

VCC_BATT_IN: 9-12.6V

We are using the 3 cell battery pack directly in which we done have the access of each individual cell, we are getting directly 3 cell voltage which ranges from 9V to 12.6V

Please find the below attached schematic:

Hello,

I review the schematic and I do not see any obvious mistakes. I don't regularly see the design choice used for the communication lines however, that should not be a problem.

Regards,

Adrian

HI Adrian

Thanks for sharing the feedback. i have some doubt regarding the mosfet circuitry and there resistor divider values, kindly help to check that values once.

Hello Udesh,

Thank you for drawing my attention to that part of the schematic.

Those resistors are not needed. Also, there should be a 3300pF cap between FG_BAT and ground. I am referencing our EVM schematic when reviewing your schematic. www.ti.com/.../sluubi1a.pdf

Adrian
