Low-Power, 1% Accurate, Dual-/Triple-/Quad-Level
Battery Monitors in Small TDFN and TQFN Packages
General Description
The MAX6782–MAX6790 are low-power, 1% accurate,
dual-/triple-/quad-level battery monitors offered in small
TDFN and TQFN packages. These devices are ideal for
monitoring single lithium-ion (Li+) cells, or multicell alka-
line/NiCd/NiMH power sources. These devices feature
fixed and adjustable hysteresis options to eliminate out-
put chattering associated with battery-voltage monitors.
The MAX6782/MAX6783 offer four battery monitors in a
single package with factory-set (0.5%, 5%, 10%) or
adjustable hysteresis. The MAX6784/MAX6785 provide
three battery monitors with factory-set (0.5%, 5%, 10%)
or adjustable hysteresis. The MAX6786/MAX6787/
MAX6788 offer two battery monitors with external inputs
for setting the rising and falling thresholds, allowing
external hysteresis control. The MAX6789/MAX6790 fea-
ture quad-level overvoltage detectors with complemen-
tary outputs.
The MAX6782–MAX6790 are offered with either open-drain
or push-pull outputs. The MAX6782/MAX6784/MAX6786/
MAX6789 are available with push-pull outputs while the
MAX6783/MAX6785/MAX6787/MAX6790 are available with
open-drain outputs. The MAX6788 is available with one
open-drain output and one push-pull output (see the
Selector Guide).
This family of devices is offered in space-
saving TDFN and TQFN packages and is fully specified
over the -40°C to +85°C extended temperature range.
