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. This design also minimizes overall power consumption under dynamic conditions. Large internal output drivers allow railto-rail output swing with loads up to 6mA. All devices are available in the ultra-small 8-pin SOT23 package. Refer to the MAX9117–MAX9120 data sheet for similar single comparators with or without reference in a tiny SC70 package.
