... Rails™ inputs and are guaranteed to operate down to +1.6V. The MAX9117/MAX9118 feature an on-board 1.252V ±1.75% reference and draw an ultra-low supply current of only 600nA, while the MAX9119/MAX9120 (without reference) require just 350nA of supply current. These features make the MAX9117–MAX9120 family of comparators ideal for all 2-cell battery-monitoring/man- agement applications ...

... Detailed Description The MAX9117/MAX9118 feature an on-board 1.252V ±1.75% reference, yet draw an ultra-low supply current of 600nA. The MAX9119/MAX9120 (without reference) consume just 350nA of supply current. All four devices are guaranteed to operate down to +1.6V. Their com- mon-mode input voltage range extends 200mV beyond-the-rails. Internal hysteresis ensures clean out- put switching, even with slow-moving input signals ...

... IN- has a fixed voltage applied, and IN+ is varied. If the inputs were reversed, the figure would be the same, except with an inverted output. Additional Hysteresis (MAX9117/MAX9119) The MAX9117/MAX9119 have a 4mV internal hysteresis band (V HB with three resistors using positive feedback (Figure 3). ...

... They have open-drain outputs and require an external pullup resistor (Figure 4). Additional hysteresis can be generated using positive feedback, but the for- ). For this HB mulas differ slightly from those of the MAX9117/ MAX9119. Use the following procedure to calculate resistor values Select R3 according to the formulas the two resulting resistor values ...

... Zero-Crossing Detector Figure 5 shows a zero-crossing detector application. The MAX9119’s inverting input is connected to ground, and its noninverting input is connected to a 100mV signal source. As the signal at the noninverting input crosses 0V, the comparator’s output changes state. ...
