Li+ Battery-Pack Protector with
Integrated Fuse Driver
General Description
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.
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.
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.
The low-cost MAX1906 is available in a thermally
enhanced 16-pin QFN package.
