Charge Algorithm
5.7 Charge Suspend
The device can suspend charging at high and low temperatures to prevent damage of the cells. Care
should be taken to ensure Charge Inhibit and Charge Suspend features are configured correctly as upon
Charge Suspend detection [CHGSU=1], then Charge Inhibit detection criteria will have to be passed prior
to restarting charge.
