Maxim MAX917ESA+

带电压基准CMOS，推挽式，满摆幅，TTL95µs

Overview

The MAX917–MAX920 nanopower comparators in space-saving SOT23 packages feature Beyond-the-Rails inputs and are guaranteed to operate down to +1.8V. The MAX917/MAX918 feature an on-board 1.245V ±1.5% reference and draw an ultra-low supply current of only 750nA, while the MAX919/MAX920 (without reference) require just 380nA of supply current. These features make the MAX917–MAX920 family of comparators ideal for all 2-cell battery applications, including monitoring/management. 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 MAX917/MAX919 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 8mA. The MAX918/MAX920 have an open-drain output stage that makes them suitable for mixed-voltage system design.
