Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
DescriptionThe 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 0.85A (MAX9019/MAX9020), 1A (MAX9015/MAX9016), or 1.2A (MAX9017/MAX9018) makes the MAX9015 MAX9020 family of comparators ideal for all 2-cell battery monitoring/management applications.
The unique design of the MAX9015MAX9020 output stage limits supply-current surges while switching, which virtually eliminates the supply glitches typical of many other comparators. This design also minimizes overall power consumption under dynamic conditions. The MAX9015/MAX9017/MAX9019 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 6mA. The MAX9016/MAX9018/MAX9020 have an open-drain output stage that makes them suitable for mixed-voltage system design. MAX9015 are available in the ultra-small 8-pin SOT23 package.
