MAX9015

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 0.85A (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. All devices are available in the ultra-small 8-pin SOT23 package.
