(Notes)
       Polarity of current:
            The direction of current flowing into the IC is considered positive(+).
            The direction of current flowing out of the IC is considered negative(-).
            The voltage impressed on the open collector output terminal should be the absolute maximum voltage of the power supply.
            The voltage difference between the negative terminal of the battery and the GND terminal should be 0V~0.6V.


Description

M62256FP is a semiconductor integrated circuit designed to control the battery charger. This IC controls not only all the time sequence needed for battery charging,but also gives full support for detection of battery temperature,protection over current and voltage,and safety timer,etc. It is also a simple matter to charge Ni-Cd,Ni-MH batteries by adding a small peripheral components to this IC.

This M62256FP IC has a feedback controlling of the charge current and the output voltage.
