Linear Comparators are components used in analog/digital circuits to compare two input signals and drive the output when one to two conditions or comparison thresholds are met. The LMC6772BIMX/NOPB is part of a family of accurate, low power, single supply comparator. It is designed to operate with supply currents as low as 2uA and is accessible in the tiny SOT-23 package.

The LMC6772BIMX/NOPB features two inputs: IN+ and IN-. These inputs can be used to make a voltage comparison between the two, and an output pin is provided to indicate when a point of comparison has been achieved. Its output is capable of sinking or sourcing up to 10mA of current, and it features a shutdown mode for power savings. When the enable pin is asserted to a logic high level then the input pins are fully functional and the comparator will produce a solution in less than 3uS.

The main application field of the LMC6772BIMX/NOPB is in low power battery powered applications requiring precision comparison and low current draw. It is particularly suited to battery-backed systems that require an efficiency threshold to keep power draw low. It is also ideal for voltage monitoring and switch detection, as it can detect fine-grained power fluctuations and then act accordingly without drawing too much current.

The working principle of the LMC6772BIMX/NOPB is based on the comparison of an input voltage to an internal reference voltage. When the comparator senses that the voltage at its "+" input is greater than its "-" input, it will drive the output low. Conversely, when the voltage at its "+" input is lesser than its "-" input, the output will be driven high. This basic dual-level operation allows for quick observations of two different comparison levels.

The LMC6772BIMX/NOPB also features a strobe input which enables the comparator to compare the voltage of its two inputs at discrete intervals, instead of continuously. This strobe input requires a logic high or logic low from an external source to enable the comparison, and the comparator will then drive its output accordingly. This strobe functionality increases the accuracy of the comparator as it will compare the input voltages based on predetermined set points.

In summary, the LMC6772BIMX/NOPB is a low power, single-supply comparator that is perfect for precision voltage comparison and switch detection. It is especially suitable for battery-backed systems, as it allows efficient and accurate decision making without drawing too much current. The modular configuration of the comparator also allows for easy implementation in a variety of applications.
