General Description
The MAX9025–MAX9028 nanopower comparators in
space-saving chip-scale (UCSP) packages feature
Beyond-the-Rails inputs and are guaranteed to oper-
ate down to +1.8V. The MAX9025/MAX9026 feature an
on-board 1.236V ±1% reference and draw an ultra-low
supply current of only 1A, while the MAX9027/
MAX9028 (without reference) require just 0.6A of supply
current. These features make the MAX9025–MAX9028
family of comparators ideal for all 2-cell battery-
monitoring/management applications.
The unique design of the output stage limits supply-
current surges while switching, virtually eliminating the
supply glitches typical of many other comparators. This
design also minimizes overall power consumption under
dynamic conditions. The MAX9025/MAX9027 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 MAX9026/MAX9028
have an open-drain output stage that makes them suit-
able for mixed-voltage system design. All devices are
available in the miniature 6-bump UCSP packages.
Refer to the MAX9117 data sheet for similar comparators
in 5-pin SC70 packages and the MAX9017 data sheet for
similar dual comparators in 8-pin SOT23 packages.
