SOT23, 1.8V, Nanopower, Beyond-the-Rails Comparators With, Without Reference
General Description
The MAX917 MAX920 nanopower comparators in space-saving SOT23 packages feature Beyond-theRails™ 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.
