MAX918EUK + T IC COMPARATOR 1 W/VOLT REF SOT23 1.8V ~ 5.5V 5mV @ 5V
Comparator with Voltage Reference Open-Drain, Rail-to-Rail SOT-23-5
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.
