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.
