UCSP, 1.8V, Nanopower, Beyond-the-Rails Comparators With/Without Reference
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 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 batterymonitoring/management applications. The unique design of the output stage limits supplycurrent surges while switching, virtually eliminating the supply glitches typical of many other comparators.
