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.
