Battery-Pack Fault Monitors
General Description
The MAX11080/MAX11081 are battery-pack fault-moni-
tor ICs capable of monitoring up to 12 lithium-ion (Li+)
battery cells. This device is designed to provide an
overvoltage or undervoltage fault indication when any
of the cells cross the user-selectable threshold for
longer than the set program-delay interval. The over-
voltage levels are pin selectable from +3.3V to +4.8V
in 100mV increments, and have a guaranteed accura-
cy of ±25mV over the entire temperature range. The
undervoltage level is also user selectable from +1.6V
to +2.8V in 200mV increments. These levels are guar-
anteed to ±100mV over the entire temperature range.
Undervoltage detection can be disabled as one of the
user-configuration options.
The MAX11080/MAX11081 have a built-in level-shifter
that allows up to 31 MAX11080/MAX11081 devices to
be connected in a daisy-chain fashion to reduce the
number of interface signals needed for large stacks of
series batteries. Each cell is monitored differentially and
compared to the overvoltage and undervoltage thresh-
olds. When any of the cells exceed this threshold for
longer than the set program delay interval, the
MAX11080/MAX11081 inhibit the heartbeat signal from
being passed down the daisy-chain. Built-in compara-
tor hysteresis prevents threshold chattering.
The MAX11080/MAX11081 are designed to be the per-
fect complement to the MAX11068 high-voltage mea-
surement IC for redundant fault-monitoring applications.
This device is offered in a 9.7mm x 4.4mm, 38-pin
TSSOP package with 0.5mm pin spacing. The package
is lead-free and RoHS compliant with an extended
operating temperature range of -40°C to +105°C.
