6V, Nanopower, Beyond-the-Rails Comparators With/Without Reference
General Description
The MAX9117–MAX9120 nanopower comparators in space-saving SC70 packages feature Beyond-theRails™ 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/management applications.
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 MAX9117/MAX9119 have a push-pull output stage that sinks and sources current.
Large internal-output drivers allow rail-to-rail output sw...
