BQ40Z50-R1: Term Min Cell V setting

user4576477

Part Number: BQ40Z50-R1

Dear TI members,

According to BQ40Z50-R1 data memory setting default value, I'm confused about Term Min Cell V setting. I think it should be Term Voltage divider by number of cell series (9000mV/3=3000mV) or setting by cell's end of discharge voltage, but it's 2800mV. What's reason for Term Min Cell V setting=2800mV?

This is just an example default setting. Since either "Term Voltage" or "Tem Min Cell V" will be used based on your [CELL_TERM] settings, it can be adjusted for your application. What it is trying to show here is that if for example Cell1 V = 3100mV, Cell2 V = 2800mV and Cell3 V = 3100mV it will have similar termination behavior whether [CELL_TERM] = 0 or 1.
I hope this makes sense.

Swami
