Tool/software:
Hi TI team,
I hope you are well. I am currently making a powerbank which will use 9 LiHV cells in series that have the voltage range of 3.35V - 4.5V/cell, and BQ77216 seems to be the perfect solution for me, since it is one of the only devices that allows a low-voltage cutoff well past 3V and doesn't require programming. However, there are, of course, no variants of the device that have suitable OVP and UVP thresholds. They seem to all be intended for variants of LCO, LFP, and older (lower-nickel) NMC/NCA chemistries - definitely none that would have thresholds suitable for my application's battery chemistry, which I'm sure will start to become more common as other consumer electronics companies start to phase out 100% LCO cathodes and move towards high-nickel NMC/NCA and other changes to increase nominal voltage.
Could you please give me a quick rundown on what the process would look like to make a new device that supports these thresholds, and what the MOQ is for something like this? Are we talking a few hundred, a reel of 2000, or a few hundred reels of 2000?
Thank you so much.
Kind regards,
Rain
