Other Parts Discussed in Thread: TIDA-00108,
Hi,
I saw TIDA-00108 using 3 pcs BQ7718 for stack.
My question is "tiduck7.pdf" table 2, it decribe for calculate Vgs.
Why it use 20V/20V/45V?
the Buttom device each cell 4.2V and the highest is 4.3V, then 4.2* 4 + 4.3 equal 21.1V. not 20V.
the Top device should be 63.1V.
also, how does come the 6.67V? and why top device isn't 20.01V?
