MAX920 datasheet



The MAX917 thru 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 (with out reference) require just 380nA of supply current.

These features make the device family of comparators ideal for all 2-cell battery applications, including monitoring/management.
