SOT23, Dual, Precision, 1.8V, Nanopower

Comparators With/Without Reference

General Description

Features

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 1ꢀ ref-

erence, while the B-grade packages feature a 1.24V

1.75ꢀ reference. An ultra-low supply current of 0.85ꢁA

(MAX9019/MAX9020), 1ꢁA (MAX9015/MAX9016), or

1.2ꢁA (MAX9017/MAX9018) makes the MAX9015–

MAX9020 family of comparators ideal for all 2-cell bat-

tery monitoring/management applications.

Beyond-the-ꢁails

ꢀ CMOS Push-Pull Output with 6mA Driꢃe

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.
