Part Number: TIDA-00449 Other Parts Discussed in Thread: BQ76930 dear TI's partner,
In TIDA-00449 design reference, i find the LDO (Regout pin) output voltage is from Regsrc pin. meanwhile,the Regsrc pin voltage is from external mosfet Q3's s pole,…
The bq29700 uses 100mV between V- and VSS for the over current threshold. With a 50mA current limit the RDSon of the 2 fets would be 2 ohms total to achieve that. 1Ohm mosfets are not available on the TI site. So I want to use a series precision resistor…
Part Number: BQ78350 Other Parts Discussed in Thread: TIDA-00792 , TIDA-010030
Hi experts,
I made a small BMU design for a proto project and I attached its SCH below. Would you be able to check it for me? The design has 13S configuration with separate…
Hi Daniel,
It is half the voltage drop at the FET, specifically at the Vgs.
When balancing the VCx pins for that cell will pull together. The cell voltage will divide approximately between the 2 input filter resistors neglecting the internal resistance…
Part Number: BQ76930 Other Parts Discussed in Thread: BQ78350 Seeking help as to what may have caused this as so far we are unable to replicate.
Have been testing a design using the BQ76930 & BQ78350 and it has failed such that the BQ76930 was running…

Part Number: BQ24773 HI
My current customer is trying to develop 4S4P Lithium Battery Charger with BQ24773.
The circuit configuration was based on EVM.
I have the following questions in the following circuit configuration.
1. Connection part of…
Hello Vish,
Thanks for the quick reply.
There is one deviation from the cell connections recommended in the bq76930 datasheet for a 7S battery and that will be changed when we respin the board. I'm hoping it won't cause any problems for now. Cell…

Part Number: TUSB2046B Hi,
We are using TUSB2046 Hub in our design for managing 3 ports and we used USB MuX Switch also for this purpose. We gonna use OTG USB from our target device processor.
Please anybody review the circuits to confirm this design…
