Part Number: BQ77915 Hello,
I'm looking for a three cell (LiPo) charge balancing solution for my project. I found quite a few potential IC's however, none of them
will support a ground referenced battery. My system and the battery are both ground…
Part Number: BQ77915 I am attempting to understand the balancing feature of the BQ77915. When I hook up a LIPO charger(either a custom design or just a CC/CV COTs charger) like the

Hi Janardhan,
Do you have a schematic with both ICs stacked and how the two are connected? I'm assuming some of these components are not populated depending on if it is the upper or lower device, but it would be helpful if I could see how the board is actually…
Part Number: BQ77915 Hi
The customer design with BQ77915.
After the battery output load is short-circuited, remove the short circuit immediately. The CHG and DSG are always low. Only when the charger is connected, the CHG and DSG pins return to high. …
Part Number: BQ77915 Hello, What is the lowest cell voltage that can be charged? With the BQ7791501, UV is 2.8V/cell at which the DSG turns OFF. Pack lies around for some time and continues to discharge itself. At what voltage is it no longer possible to…
Part Number: BQ77915 Greetings,
I am using the BQ7791502 IC as a battery protection IC for my BMS design. When I am testing the BMS in discharge conditions with a current of 70A, the discharge MOSFET's are damaging. I also checked the MOSFET datasheet…
Part Number: BQ77915 Hello Everyone
I have a question regarding this algorithm and would appreciate a detailed explanation if possible. The documentation states that balancing begins when the voltage exceeds Vstart, so why is only the C5 balancing Field…
Part Number: BQ77915 Hello Everyone,
I have a question about the differences between OCD delays. Could someone please clarify this for me? I'm struggling to understand whether these delays are the same or if they differ, and what their applications might…
Part Number: BQ77915 I have been recently working on BQ7791500PWT for a 5 cell Li-ion based application and facing some issues while troubleshooting. I had the following design related questions -
1. What is the recommended voltage input rating for the…
