MAX9644/MAX9645/
MAX9646
nanoPower Comparators with
Precision Reference in 4-Bump UCSP
General Description
The MAX9644/MAX9645/MAX9646 are small, single
comparators, 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 UCSP™ package with a 1mm
x 1mm footprint (as small as two 0402 resistors) and a
5-pin SOT23 package.
The ICs feature an input voltage range of -0.3V to +5.5V,
independent of supply voltage. These devices maintain
high impedance at the inputs even when powered down
(VCC or VREF = 0V). They also feature internal filtering to
provide high RF immunity.
The ICs have an internal 0.2V reference. These devices
feature either a push-pull or an open-drain output. They
consume only 700nA (max) supply current and operate
down to VCC = 1V over the extended -40ºC to +85ºC
temperature range.
