Smart battery protection and monitoring IC
M61040FP
DESCRIPTION
The M61040FP is intended to be used as SB: Smart Battery.
All functions needed for SB are packed to this M61040FP. The
combination use with Microcomputer 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 microcomputer control.
The amp gain of charge/discharge current detection circuit is controlled
by microcomputer, therefore the accuracy of SB’s Remaining Capacity
Detection becomes better than before. The reset circuit and The linear
regulator for Vcc / Vref of microcomputer are dedicated in M61040FP. So

Figure1. Function after detecting over-discharge
Resume from Power Down Mode
After entering Power Down mode, the series regulator will begin operation when charger is
connected(VIN_12 pin is high). The RESET will output low to high signal when Vreg is over reset level
voltage. Microcomputer will begin operation and send command to resume M61040 from Power Down
mode.
7) Conditioning Circuit
M61040 have a discharge circuit of each cells. It is available for drop of cell voltage for safety purpose.
And to shorten the difference voltage among the cells . It can extend the battery pack life.
