The features of MAX712 and MAX713 are very similar, the difference between them is when the MAX712 detects that the dv/dt becomes zero, it will terminate fast charging mode, but the MAX713 terminates the fast charging mode when the dv/dt becomes negative; the MAX712 and MAX713 can charge 1-16 batteries, they has the linear or switch mode power control, for the linear mode, the MAX712 and MAX713 supply the power to the load of storage battery when the storage battery is charging; they has three modes to cut off the fast charge (voltage gradient, temperature or time), and they can automaticly change from the fast charging to trickle charging; when the battery is not charging, the maximum leakage current of the storage battery is only 5mA.
