... 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. ...

... As the input volt- age exceeds the supply rails, these ESD protection diodes become forward biased and begin to conduct. The MAX9025–MAX9028 contain a unique break- before-make output stage capable of rail-to-rail opera- tion with up to ±5mA loads. Many comparators consume orders of magnitude more current during switching than during steady-state operation ...
