General Description
The MAX6775–MAX6781 low-power, 1%-accurate bat-
tery monitors are available in the ultra-small DFN
package (1.0mm x 1.5mm) and SC70 packages. These
low-power devices are ideal for monitoring single lithi-
um-ion (Li+) cells, or multicell alkaline/NiCd/NiMH
power sources. These devices offer single (MAX6775/
MAX6776/MAX6777/MAX6778) or dual (MAX6779/
MAX6780/MAX6781) low-battery outputs and feature
fixed or resistor-adjustable hysteresis. Hysteresis elimi-
nates the output chatter sometimes associated with bat-
tery voltage monitors, usually due to input-voltage noise
or battery terminal voltage recovery after load removal.
These devices are available in several versions: with
single- or dual-voltage monitors, and with fixed or
adjustable hysteresis. The MAX6775/MAX6776 offer a
single battery monitor and factory-set hysteresis of
0.5%, 5%, or 10%. The MAX6779/MAX6780/MAX6781
have two battery monitors in a single package and fac-
tory-set hysteresis of 0.5%, 5%, or 10%. The MAX6777/
MAX6778 offer a single battery monitor with external
inputs for the rising and falling thresholds, allowing
external hysteresis control.
For convenient interface with system power circuitry or
microprocessors, both open-drain and push-pull out-
puts are available. The single-channel devices are
available with open-drain or push-pull outputs. The
dual-channel devices are available with both outputs
open-drain, both outputs push-pull, or one of each
(see the
Selector Guide). This family of devices is
offered in small 5-pin SC70 and ultra-small 6-pin DFN
packages, and is fully specified over the -40°C to
+85°C extended temperature range.
