General Description

The MAX9025/MAX9028 nanopower comparators in space-saving chip-scale (UCSP™) packages feature Beyond-the-Rails™ inputs and are guaranteed to operate down to +1.8V. The MAX9025/MAX9026 feature an on-board 1.236V ±1 reference and draw an ultralow 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 batterymonitoring/management applications.
