MAX9015–MAX9020
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% reference,
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 this product family of comparators ideal
for all 2-cell battery monitoring/management applications.
The unique design of the devices 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 suitable 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.
