SC70, 1.8V, Nanopower, Beyond-the-Rails  
Comparators With/Without Reference  
General Description  
Features  
The MAX9117–MAX9120 nanopower comparators in  
space-saving SC70 packages feature Beyond-the-  
Rails™ inputs and are guaranteed to operate down to  
+1.8V. The MAX9117/MAX9118 feature an on-board  
1.252V 1.75ꢀ reference and draw an ultra-low supply  
current of only 600nA, while the MAX9119/MAX9120  
(without reference) require just 350nA of supply current.  
These features make the MAX9117–MAX9120 family of  
comparators ideal for all 2-cell battery-monitoring/man-  
agement applications.  
o Space-Saving SC70 Package (Half the Size of  
SOT23)  
o Ultra-Low Supply Current  
350nA Per Comparator (MAX9119/MAX9120)  
600nA Per Comparator with Reference  
(MAX9117/MAX9118)  
o Guaranteed to Operate Down to +1.8V  
o Internal 1.252V 1.75ꢀ Reference  
(MAX9117/MAX9118)  
The unique design of the output stage limits supply-cur-  
rent surges while switching, virtually eliminating the sup-  
ply glitches typical of many other comparators. This  
design also minimizes overall power consumption under  
dynamic conditions. The MAX9117/MAX9119 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 MAX9118/MAX9120  
have an open-drain output stage that makes them suit-  
able for mixed-voltage system design. All devices are  
available in the ultra-small 5-pin SC70 package.  
o Input Voltage Range Extends 200mV  
Beyond-the-Rails  
o CMOS Push-Pull Output with 5mA Drive  
Capability (MAX9117/MAX9119)  
o Open-Drain Output Versions Available  
(MAX9118/MAX9120)  
o Crowbar-Current-Free Switching  
o Internal Hysteresis for Clean Switching  
o No Phase Reversal for Overdriven Inputs
