MAX40002–MAX40005
nanoPower 4-Bump Comparator in Ultra-Tiny
0.73mm x 0.73mm WLP/SOT23 Packages
General Description
Benefits and Features
● Tiny 0.73mm x 0.73mm, 4-Bump WLP and 5-Pin
The MAX40002–MAX40005 tiny, single comparators are
ideal for a wide variety of portable electronics applications
such as cell phones, media players, and notebooks that
have extremely tight board space and power constraints.
These comparators are offered in both, a miniature
4-bump wafer-level package (WLP) with a 0.73mm x
0.73mm footprint (as small as two 0402 resistors) and a
5-pin SOT23 package.

The MAX40002–MAX40003 have open-drain outputs,
while the MAX40004–MAX40005 feature push-pull outputs.
The MAX40002/MAX40004 have noninverting inputs,
while the MAX40003/MAX40005 have inverting inputs
(see the Selector Guide for more information).

These devices also come with an internal reference. The
reference voltage is preset at the factory and parts are
offered with the following voltage options: 0.2V, 0.5V, or
1.222V (see Ordering Information table).
These devices are fully specified over -40°C to +125°C
automotive temperature range.
