The MAX9018BEKA+T is a dual precision nanopower comparator with reference in 8 pin SOT-23 package. It has beyond the rails inputs and operates down to 1.8V. An ultra low supply current of 1.2μA makes the MAX9018 as ideal device for all 2 cell battery monitoring/management applications. The unique design of 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 MAX9018 has an open-drain output stage that makes it suitable for mixed voltage system design. It is typically used in ultra low power systems, threshold detectors/discriminators, window detectors, telemetry and remote systems, sensing at ground or supply line.
