Part Number: BQ77915 Hey Guys,
I appreciate your help with the schematic(s)
Is there a way to validate my BMS design(s) for mass production ? Like testing for the rated current, ESD robustness and overall approval for use in end products
Are there any…
Part Number: BQ77915 Hello guys, I have designed a 6S BMS circuit using two BQ7791506 ICs in stacked configuration. Their DSG pins work fine and output about 10V for both upper and lower ICs while their CHG pins output -2V for upper IC and 0V for lower…
Part Number: BQ77915 Hello,
I would like to configure the OCD thresholds and delay option for the BQ7791500 IC however I cannot find any information on how this is done. The datasheet states various options for the thresholds and delay times. See attached…
Part Number: BQ77915 Hello,
I would be greateful if I could get a schematic design review for my circuit based around BQ7791500 IC.
The requirements for the circuit were:
- 5S Li-ion cells
- 80A discharge current nominal
- 10A charge current nominal
…
Part Number: BQ77915 Hello TI Engineer,
I almost done with my schematics using BQ7791514.
Below are the requirements:
Battery Pack requirement
External Charger used
Cells requirement
Nominal Voltage = 12.8V
Voltage = 14.6V
Chemistry = …
Thanks, Max.
One more question for overcurrent recovery. When overcurrent charge happens, BQ77915 turns off FET of CHG. LD pin gets a close voltage of PACK- and the voltage of Vss is higher than VLD. If the charge needs to get recovered, does the charger…
Part Number: BQ77915 Hi
The customer design with BQ77915, the problem is can not enter the OCC protection.
Please help check the schematic.
Waiting for your reply.
Thanks

Part Number: BQ77915 Hi TI team,
Need support on cell balancing circuit values. My max charge current is 2.1A from external charger.
1. Please refer below schematics, I have used RINI = 1.5K, CINI = 0.1uF. Can i use these values?
2. For ESD protection,…
Part Number: BQ77915 Hello,
We are interested in using the BQ7791500 in our battery system and are wondering if it is possible to somehow modify the Load Removal function into Charger Removal function.
We will never remove the load since our application…
