General Description
The MAX9644/MAX9645/MAX9646 are small, single com-
parators, 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 pow-
ered down (VCC or VREF = 0V). They also feature inter-
nal 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 -40°C to +85°C tem-
perature range.
