Datasheet
The MAX9100/MAX9101 micropower comparators are
optimized for single-cell systems, and are fully speci-
fied for operation from a single supply of 1.0V to 5.5V.
This ultra-low voltage operation, 5µA quiescent current
consumption, and small footprint make the
MAX9100/MAX9101 ideal for use in battery-powered
systems. A wide-input common-mode range that
includes the negative rail and rail-to-rail output swing
allows almost all of the power supply to be used for sig-
nal voltage. In addition, propagation delay is less than
4µs, and rise and fall times are 100ns.
The MAX9100 features a push-pull CMOS output stage
that sinks and sources current with large internal output
drivers that allow rail-to-rail output swings with loads up
to 5mA.The MAX9101 has an open-drain output stage
that makes it suitable for mixed-voltage designs.
The MAX9100/MAX9101 are available in tiny SOT23-5
packages.

... Additionally, the supply current will typically increase to 7µA. Otherwise, the device functions as within the specified common-mode range. See graphs in the Typical Operating Characteristics. The MAX9100/MAX9101 contain a unique output stage capable of rail-to-rail operation. Many comparators consume orders of magnitude more current during switching than during steady-state operation. However, with this family of comparators, the supply-current change during an output transition is extremely small ...

... Micropower SOT23 Comparators Open-Drain Output (MAX9101) The MAX9101 has an open-drain output, which can be pulled up to +6.0V above ground independent of the supply voltage. This is typically used with an external pullup resistor, facilitating interface between mixed logic voltages. Alternatively, multiple open-drain comparator outputs can be connected in a wired-OR configuration. ...
