MAX9015–MAX9020  
SOT23, Dual, Precision, 1.8V,  
nanoPower Comparators  
With/Without Reference  
General Description  
Benefits and Features  
Ultra-Low Total Supply Current  
• 0.85μA (MAX9019/MAX9020)  
• 1.0μA (MAX9015A/MAX9016A)  
• 1.2μA (MAX9017/MAX9018)  
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.  
Guaranteed Operation Down to 1.8V  
Precision V  
< 5mV (max)  
OS  
● Internal 1.236V ±1% Reference (A Grade)  
Input Voltage Range Extends 200mV  
Beyond-the-Rails  
CMOS Push-Pull Output with ±6mA Drive Capability  
(MAX9015/MAX9017/MAX9019)  
Open-Drain Output Versions Available  
(MAX9016/MAX9018/MAX9020)  
Crowbar-Current-Free Switching  
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.  
Internal 4mV Hysteresis for Clean Switching  
No Phase Reversal for Overdriven Inputs  
Dual Versions in Space-Saving 8-Pin SOT23 Package  
AEC-Q100 Grade 3 Qualified, Refer to Ordering
