General Description
MAX40070/MAX40072 is a family of single micropower
comparators ideal for a wide variety of battery operated
devices in computing, industrial, medical, and IoT applications
that have extremely tight board space and power
constraints while requiring high levels of precision. These
comparators are offered with an open-drain output in a
small 8-bump (0.35μm pitch) wafer level package as well
as a TDFN package.
The MAX40070/MAX40072 family features a rail-to-rail input
voltage range of 0V to +27.5V on IP pin, independent
of the supply voltage. It also features internal filtering to
provide high EMI immunity.
The MAX40070/MAX40072 uses a high-precision integrated
reference voltage (1.6V) as well as a precision internal
current source that allows customized comparator
threshold and hysteresis by using two external resistors.
These comparators consume only 16μA (typ) supply current
with a propagation delay of 2μs. They all operate over
the extended -40°C to +125°C temperature range.
