battery charging
The purpose is to block current in both directions, so that neither the solar panel is charging when MOSFET is off, nor is the battery discharging into the panel (very low current, but still there and might affect both the panel and battery life), in case the charging IC doesn''t block reverse current into the panel. $endgroup$ –
Cutoff voltage
In batteries, the cut-off (final) voltage is the prescribed lower-limit voltage at which battery discharge is considered complete. The cut-off voltage is usually chosen so that the maximum useful capacity of the battery is achieved. The cut-off voltage is different from one battery to the other and it is highly dependent on the type of battery and the kind of service in which the battery is used. When t

Why does a lithium ion Charger cut off the applied voltage?
It seems standard for a lithium-ion charger to cut off the applied voltage when the CV-mode current draw dips below 0.1C (or thereabouts). Why is this necessary? Why can't the charger continue to apply 4.2V indefinitely? According to Battery University: Li-ion cannot absorb overcharge. When fully charged, the charge current must be cut off.
What is auto-voltage cut off?
Here is what I mean by auto-voltage cut off (focus on the blue and black voltage curve): V (in) is the input voltage of the an auto cutoff circuit and V (v_dc) is the output of this circuit (and is connected to the battery).
