MAX917, MAX918, MAX919, MAX920 SOT23, 1.8V, Nanopower, Beyond-the-Rails Comparators With/Without Reference

The MAX917 MAX918 MAX919 MAX920 nanopower Comparators in space-saving SOT23 packages feature Beyond-the-Rails" inputs and are guaranteed to operate down to +1.8V. The MAX917 MAX918 feature an on-board 1.245V 1.5% reference and draw an ultra-low supply current of only 750nA, while the MAX919 MAX920 (without reference) require just 380nA of supply current. These features make the MAX917 MAX920 family of Comparators ideal for all 2-cell battery applications, including monitoring/management.
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 MAX917 MAX919 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 8mA. The MAX918 MAX920 have an open-drain output stage that makes them suitable for mixed-voltage system design.
