Advanced Li+ Battery-Pack Protectors
General Description
The MAX1894/MAX1924 are lithium-ion/lithium-polymer (Li+) battery-pack protector ICs for 3- or 4-series Li+ battery packs.
The MAX1894/MAX1924 enhance the useful operating life of Li+ batteries by monitoring individual cell voltages and preventing over/undervoltage conditions.
The MAX1894/MAX1924 also protect the battery pack against charge current, discharge current, and packshort fault conditions.
In case of a fault condition, on-board drivers control external P-channel MOSFETs, which disconnect the cells from the pack external terminals.
The external protection MOSFETs are connected in a common-source configura...
