Update: 30 September, 2023
The MAX9025-MAX9028 ultra-low-power comparators are integrated circuits in a space-saving chip-scale (UCSP) package with Beyond-the-Rails inputs that are guaranteed to operate down to +1.8V. The MAX9025/MAX9026 feature an on-board 1.236V ±1% reference and draw an ultra-low supply current of only 1µA, while the MAX9027/MAX9028 (without reference) require just 0.6µA of supply current. These features make the MAX9025-MAX9028 family of comparators ideal for all 2-cell battery-monitoring/management applications. The unique design of the output stage limits supply-current surges while switching, virtually eliminating the supply glitches typical of many other comparators. This design also minimizes overall power consumption under dynamic conditions. The MAX9025/MAX9027 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 MAX9026/MAX9028 have an open-drain output stage that makes them suitable for mixed-voltage system design. All devices are available in the miniature 6-bump UCSP packages. For similar comparators in 5-pin SC70 packages, refer to the MAX9117 data sheet, and for similar dual comparators in 8-pin SOT23 packages, refer to the MAX9017 data sheet. Applications include 2-cell battery monitoring/management, ultra-low-power systems, mobile communications, notebooks and PDAs, sensing at ground or supply line, telemetry and remote systems, and medical instruments.
