Protection of Lithium Ion Batteries (four cells in series) MM1294
Protection of Lithium Ion Batteries (four cells in series)
Monolithic IC MM1294
Outline
This IC provides protection for lithium ion batteries in the event of overcharging, overdischarging and
overcurrents. When anomalies occur during charging or at other times and excessive voltages are applied,
after a certain time has elapsed for each cell an external FET switch is turned off (overcharging detection); and
in order to prevent overdischarge of the battery during discharge, when the voltage of individual batteries falls
below a fixed voltage, an external FET switch is turned off (overdischarge detection), and the IC is put into
low-consumption current mode. When large currents flow due to a short-circuit or other cause, an external
MOS switch is turned off (overcurrent detection).
Package
