General Description
The MAX1894/MAX1924 are lithium-ion/lithium-polymer (Li+) battery-pack protector ICs for 3- or 4-series Li+ bat tery 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 pack short fault conditions.
Features
? Protect Against Cell Overvoltage
Factory Programmable Limits from 4V to 4.4V Accurate to ±0.5
? Protect Against Cell Undervoltage Factory Programmable Limits from 2V to 3.2V Accurate to ±2.0
? Protect Against Charge, Discharge, and Pack Short Current Faults
? Automatically Trickle Charges Deeply Discharged Cells
? Fully Integrated MOSFET Drivers Do Not Require Pullup Resistors
? 0.8μA (typ) Shutdown Supply Current Prevents Deep Discharge of Cells
? 30μA (typ) Operating Supply Current
? 28V (max) Input Voltage
? Available in Small 16-Pin QSOP Package
Applications
3- or 4-Series Li+ Battery Packs
