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

No Phase ꢁeꢃersal ꢂor Oꢃerdriꢃen Inputs  
®
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.
