Partial pressure influences, and in-phase end voltage is computed showing that virtual voltage is changed into 2.8V.Now cell voltage 3V, in-phase end 2.8V, reversely
Hold 3V, output end output low level.It is computed, when cell voltage reaches 3.2V (the 3rd setting voltage), in-phase end voltage is
Reach 3V, comparator output high level.Therefore, comparator realizes that 3V is turned off, 3.2V can just be led in the case of reference voltage 3V
