MAX9118

The MAX9118 nanopower comparators in space-saving SC70 packages feature Beyond-the-Rails™ inputs and are guaranteedto operate down to +1.8V. The MAX9117/MAX9118 feature an on-board 1.252V ±1.75% reference and draw an ultra-low supply current of only 600nA, while the MAX9119/MAX9120 (without reference) require just 350nA of supply current. These features make the MAX9118 comparators ideal for all 2-cell battery-monitoring/management applications.

The unique design of the output stage limits supply-current of MAX9118 surges while switching, virtually eliminating the supply glitches typical of many other comparators. This design also minimizes overall power consumption under dynamic conditions. The MAX9117/MAX9119 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 5mA. The MAX9118/MAX9120 have an open-drain output stage that makes them suitable for mixed-voltage system design. All devices are available in the ultra-small 5-pin SC70 package.
