Datasheet Maxim MAX920EUK-T — Даташит

19-1512; Rev 2; 10/10 SOT23, 1.8V, Nanopower, Beyond-the-Rails
Comparators With/Without Reference
The MAX917-MAX920 nanopower comparators in
space-saving SOT23 packages feature Beyond-theRails^TM 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. Features
