MAX9025–MAX9028  
UCSP, 1.8V, nanoPower, Beyond-the-Rails  
Comparators With/Without Reference  
General Description  
Features  
● Space-Saving UCSP Package (1mm x 1.52mm)  
The MAX9025/MAX9028 nanopower comparators in  
space-saving chip-scale (UCSP™) packages feature  
Beyond-the-Rails™ inputs and are guaranteed to oper-  
ate down to +1.8V. The MAX9025/MAX9026 feature  
an on-board 1.236V ±1% reference and draw an ultra-  
low supply current of only 1µA, while the MAX9027−  
MAX9028 (without reference) require just 0.6µA of  
supply current. These features make the MAX9025−  
MAX9028 family of comparators ideal for all 2-cell battery-  
monitoring/management applications.  
● Ultra-Low Supply Current  
• 0.6µA (MAX9027/MAX9028)  
• 1µA with Reference (MAX9025/MAX9026)  
● Guaranteed to Operate Down to +1.8V  
● Internal 1.236V ±1% Reference (MAX9025/  
MAX9026)  
● Input Voltage Range Extends 200mV  
Beyond-the-Rails  
● CMOS Push-Pull Output with ±5mA Drive Capability  
(MAX9025/MAX9027)  
● Open-Drain Output Versions Available (MAX9026/  
The unique design of the output stage limits supply-  
current surges while switching, virtually eliminating the  
supply glitches typical of many other comparators. This  
design also minimizes overall power consumption under  
dynamic conditions. The MAX9025/MAX9027 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 5mA. The MAX9026/MAX9028 have an  
open-drain output stage that makes them suitable for  
mixed-voltage system design. All devices are available in  
the miniature 6-bump UCSP packages.
