Nano Power, Push/Pull Output Comparator
ISL28915
The ISL28915 is a nano power comparator optimized for
low-power applications. This device is designed for
single-supply operation from 1.8V to 5.5V and typically
consumes 500nA of supply current. These devices also feature
a push/pull output stage with rail-to-rail input and output
swing (RRIO), allowing for maximum battery usage.
The combination of small footprint, low power, single supply,
and rail-to-rail operation makes them ideally suited for all
battery operated devices.
The ISL28915 features an enable pin and is offered in the
6 Ld SOT-23 package. The device operates over the -40°C to
+125°C temperature range.
