General Description
The MAX44268 is an ultra-small and low-power dual
comparator ideal for battery-powered applications such
as cell phones, notebooks, and portable medical devices
that have extremely aggressive board space and power
constraints. The comparator is available in a miniature
1.3mm x 1.3mm, 9-bump WLP package, making it the
industry’s smallest dual comparator.
The IC can be powered from supply rails as low as 1.8V
and up to 5.5V. It also features a 1.236V ±1% reference
and a 0.7A typical supply current per comparator. It has
a rail-to-rail input structure and a unique output stage that
limits supply current surges while switching. This design
also minimizes overall power consumption under dynam-
ic conditions. The IC has open-drain outputs, making it
suitable for mixed voltage systems. The IC also features
internal filtering to provide high RF immunity. It operates
over a -40°C to +85°C temperature.
