Advanced Lithium-Ion  
Battery-Pack Protector  
MA16SV/X  
General Description  
Features  
The MAX1666 provides complete protection against over-  
voltage, undervoltage, overcharge current, overdischarge  
current, and cell mismatch for 2-cell to 4-cell Lithium-Ion  
battery packs. The voltage of each cell in the battery pack  
is checked and compared to the programmable threshold  
and to the other cells in the pack.  
♦ Overvoltage Protection  
Programmable Limits from +4.0V to +4.4V  
Accurate to ±0.5%  
♦ Undervoltage Protection  
Programmable Limits from +2.0V to +3.0V  
Accurate to ±2.5%  
The MAX1666 protects the battery pack in an overcurrent  
condition by disconnecting the pack from the load at a pro-  
grammable limit. On-chip power MOSFET drivers control  
external P-channel MOSFETs to disconnect the cells from  
external terminals when faults occur.  
♦ Cell Mismatch Protection  
Programmable Limits from 0 to 500mV  
Accurate to ±10%  
♦ Overcharge Current Protection  
♦ Overdischarge Current Protection  
♦ Low Operating Supply Current: 30µA typ  
♦ Low Standby Current: 1µA max  
♦ +28V max Input Voltage  
The MAX1666 employs a unique timing scheme that allows  
three modes of operation, for optimal performance and bat-  
tery power conservation. The MAX1666 can operate in a  
stand-alone configuration or in conjunction with a micro-  
controller. It is available in three versions: the “S” version  
monitors two Li-Ion cells, the “V” version monitors three  
cells, and the “X” version monitors four cells.  
♦ Available in Small 16-Pin QSOP (MAX1666S) and  
20-Pin QSOP (MAX1666V/X) Packages
