General Description
The MAX9117–MAX9120 nanopower comparators in
space-saving SC70 packages feature Beyond-the-
Rails inputs and are guaranteed to operate down to
+1.8V. The MAX9117/MAX9118 feature an on-board
1.252V ±1.75% reference and draw an ultra-low supply
current of only 600nA, while the MAX9119/MAX9120
(without reference) require just 350nA of supply current.
These features make the MAX9117–MAX9120 family of
comparators ideal for all 2-cell battery-monitoring/man-
agement applications.
The unique design of the output stage limits supply-cur-
rent surges while switching, virtually eliminating the sup-
ply glitches typical of many other comparators. This
design also minimizes overall power consumption under
dynamic conditions. The MAX9117/MAX9119 have a
push-pull output stage that sinks and sources current.
Large internal-output drivers allow Rail-to-Rail
output
swing with loads up to 5mA. The MAX9118/MAX9120
have an open-drain output stage that makes them suit-
able for mixed-voltage system design. All devices are
available in the ultra-small 5-pin SC70 package.
