... 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. The unique design of the output stage limits supply-cur- rent surges while switching, virtually eliminating the sup- ply glitches typical of many other comparators ...

... Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. ELECTRICAL CHARACTERISTICS—MAX9117/MAX9118 (with REF +5V, V ...

... SC70, 1.6V, Nanopower, Beyond-the-Rails Comparators With/Without Reference Reference (MAX9117/MAX9118) The internal reference in the MAX9117/MAX9118 has an output voltage of +1.252V with respect to V temperature coefficient is 100ppm/°C over the full -40°C to +85°C temperature range. The reference is a PNP emitter-follower driven by a 120nA current source (Figure 1). The output impedance of the voltage refer- ence is typically 200kΩ ...
