Linear - Comparators is a category of electronics that are used as a form of circuit protection. The SM72375/NOPB is a device that falls into this category and is used to protect circuits from being subjected to power-on transients. This device works by detecting and turning off diverted current paths during the hiccup portion of a power-on transient.The SM72375/NOPB is a series of linear voltage comparators, consisting of seven output terminals (ET0 to ET6) which allow the device to detect a range of input voltages. These inputs are compared against a fixed reference voltage (1.2 volts), and if they exceed this voltage a voltage shift is triggered which turns off the current path.The device is used in a wide variety of applications where it is needed to safeguard circuits against power-on transients. These include automotive applications, consumer electronics, industrial and consumer power supplies, and many more.In its applications, it is typically used to protect circuits from high current or large voltage transients which would otherwise damage the circuit. This protection works by diverting the excess current and voltage away from the circuit, thereby preventing damage. The SM72375/NOPB is able to detect the excess current and voltage and shift the voltage away from the circuit before the it is able to damage the circuit.The SM72375/NOPB also features protection from reverse currents, which occur when two or more power lines are connected in series. This reverse current can cause the current path to stay steady, while the input voltage varies. The SM72375/NOPB\'s comparator circuit is able to detect this inconsistency and send its output to the circuit, cutting off the current when necessary.The SM72375/NOPB is also capable of detecting and inserting a soft start into the circuit, which is used to extend the life of the circuit by limiting the amount of inrush current during power-up. A soft start helps limit the damage to components which would otherwise be subjected to extreme current.The SM72375/NOPB\'s protection capabilities also include protection from overvoltage and overcurrent conditions which can occur when the voltage or current exceeds their normal limits. This protection works by monitoring both voltage and current, and turning off the circuit when either one of those conditions has been exceeded.In terms of its functionality, the SM72375/NOPB is an extremely versatile device. Its protection capabilities ensure that circuits are safe from a range of potentially damaging circumstances, while its soft start capability increases its versatility in applications where instantaneous power-up is not feasible. With its multiple outputs and self-diagnostics capabilities, the SM72375/NOPB is an ideal choice for circuit protection and is used in a variety of industries.
