MAX9015

SOT23, Dual, Precision, 1.8V, nanoPower Comparators With/Without Reference

Maxim Integrated 

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.
