... 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 (with- out 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 ...

... OUT Additional Hysteresis (MAX918/MAX920 REF R3 The MAX918/MAX920 have a 4mV internal hysteresis band. They have open-drain outputs and require an external pullup resistor (Figure 4). Additional hysteresis = 5V, and can be generated using positive feedback, but the for- mulas differ slightly from those of the MAX917/ MAX919 ...

... CC ⎠ The Typical Application Circuit shows an application that converts 5V logic to 3V logic levels. The MAX920 is THF powered by the +5V supply voltage, and the pullup resistor for the MAX920’s open-drain output is connect the +3V supply voltage. This configuration allows the full 5V logic swing without creating overvoltage on the 3V logic inputs ...
