1 / 14 page General Description The MAX9117–MAX9120 nanopower comparators in space-saving SC70 packages feature Beyond-the- Rails™ inputs and are guaranteed to operate down to +1.6V. The MAX9117/MAX9118 feature an on-board 1.252V ±1.75% 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. 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.
