SOT23, Dual, Precision, 1.8V, Nanopower
Comparators With/Without Reference
General Description
The single MAX9015/MAX9016 and dual MAX9017–
MAX9020 nanopower comparators in space-saving
SOT23 packages feature Beyond-the-Rails™ inputs
and are guaranteed to operate down to 1.8V. The A-
grade packages feature an on-board 1.236V ±1% ref-
erence, while the B-grade packages feature a 1.24V
±1.75% reference. An ultra-low supply current of 0.85µA
(MAX9019/MAX9020), 1µA (MAX9015/MAX9016), or
1.2µA (MAX9017/MAX9018) makes the MAX9015–
MAX9020 family of comparators ideal for all 2-cell bat-
tery monitoring/management applications.
The unique design of the MAX9015–MAX9020 output
stage limits supply-current surges while switching,
which virtually eliminates the supply glitches typical of
many other comparators. This design also minimizes
overall power consumption under dynamic conditions.
The MAX9015/MAX9017/MAX9019 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 6mA. The MAX9016/MAX9018/MAX9020
have an open-drain output stage that makes them suit-
able for mixed-voltage system design. All devices are
available in the ultra-small 8-pin SOT23 package.
Refer to the MAX9117–MAX9120 data sheet for similar
single comparators with or without reference in a tiny
SC70 package.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
