M61040FP
DESCRIPTION
The M61040FP is intended to be used as SB: Smart Battery. All functions needed for SB are packed to this M61040FP. The bination use with Microputer such as M37515 will give various functions such as a detection or calculation of SB Remaining Capacity. Over Current detection circuit dedicated in M61040FP will give safety

FET on/off control independent from microputer control. The amp gain of charge/discharge current detection circuit is controlled by microputer, therefore the accuracy of SB’ s Remaining Capacity Detection bees better than before. The reset circuit and The linear regulator for Vcc / Vref of microputer are dedicated in M61040FP. So this will help easy design of power circuit design of SB.
