SolarMagic Dual Micropower Rail-To-Rail Input CMOS
Comparator with Open Drain Output
General Description
The SM72375 is an ultra low power dual comparator with a
maximum 10 μA/comparator power supply current. It is de-
signed to operate over a wide range of supply voltages, with
a minimum supply voltage of 2.7V.
The common mode voltage range of the SM72375 exceeds
both the positive and negative supply rails, a significant ad-
vantage in single supply applications. The open drain output
of the SM72375 allows for wired-OR configurations. The open
drain output also offers the advantage of allowing the output
to be pulled to any voltage rail up to 15V, regardless of the
supply voltage of the SM72375.
The SM72375 is targeted for systems where low power con-
sumption is the critical parameter. Guaranteed operation at
supply voltages of 2.7V and rail-to-rail performance makes
this comparator ideal for battery-powered applications.
