Li+ Battery-Pack Protector with  
Integrated Fuse Driver  
General Description  
Features  
The MAX1906 protects against overvoltage conditions  
in lithium-ion/lithium polymer (Li+) battery packs by  
blowing a three-terminal protection fuse. The IC should  
be used in conjunction with resettable protection cir-  
cuits to provide a high level of safety against over-  
charging Li+ batteries. It can be used with 2-, 3-, or  
4-series cell battery packs.  
o Protects Against Overvoltage  
o ±±1 Accꢀrate Protection ꢁTresTolꢂs  
o Integrateꢂ 2.±s Faꢀlt-Delay ꢁimer  
o Bꢀilt-in ±.5A SCR Fꢀse Driver  
o ꢁest Moꢂe for Fꢀnctional Verification in  
The MAX1906 monitors individual cell voltages. If any  
cell voltage exceeds the overvoltage threshold for  
greater than 2.1s, the MAX1906 activates an internal  
SCR. The SCR sinks sufficient current to blow an exter-  
nal protection fuse, permanently disabling the battery  
pack. Alternatively, the IC can drive the gate of an  
external MOSFET to blow the fuse.  
Assembleꢂ Pack  
o 8µA (max) Sꢀpply Cꢀrrent  
o ±µA (max) Stanꢂby Cꢀrrent  
o Protects Against Disconnecteꢂ B±P–B4P Pins  
o Protects 2-, 3-, or 4-Series Li+ Battery Packs  
The MAX1906 also offers protection against disconnect-  
ed voltage sense pins. If a disconnected pin is detected,  
the DISCON output is forced low. The MAX1906 includes  
a test mode, which determines if the circuit is operating  
correctly while in an assembled battery pack.  
o Available in Small ±6-Pin QFN Package  
(5mm x 5mm)  
Ordering Information  
The low-cost MAX1906 is available in a thermally  
enhanced 16-pin QFN package.
