MAX9027 Datasheet | Maxim Integrated

Description The MAX9025- MAX9028 nanopower parators 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 parators 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 parators. 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 5m A. 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. Refer to the MAX9117 data sheet for similar parators in 5-pin SC70 packages and the MAX9017 data sheet for similar dual parators in 8-pin SOT23 packages.
