MAX9015–MAX9020
General Description
The single MAX9015/MAX9016 and dual MAX9017– MAX9020 nanoPower comparators in space-saving SOT23 packages feature Beyond-the-Rails™ inputs and are guaranteed to operate down to 1.8V. The A-grade packages feature an on-board 1.236V ±1% reference, while the B-grade packages feature a 1.24V ±1.75% reference. An ultra-low supply current of 0.85μA (MAX9019/ MAX9020), 1μA (MAX9015/MAX9016), or 1.2μA (MAX9017/ MAX9018) makes this product family of comparators ideal for all 2-cell battery monitoring/management applications. The unique design of the devices output stage limits supplycurrent surges while switching, which virtually eliminates the supply glitches typical of many other comparators.
