Multiple appliances have been developed to ease human efforts. And in the same run, numerous protective circuits are designed to ensure a long lifespan of those devices. We have seen those circuits claiming to protect … Read more
TL431
Introduction Both over and under voltages are damaging to any device or circuit. Light flickers can be caused by low voltages, while high voltages can harm the entire device or circuit. For example, in a … Read more
Overvoltage Protection Switch Circuit
The TL431 integrated circuit is a three-terminal programmable shunt regulator diode. The monolithic IC voltage references operate as a low-temperature coefficient Zener which is programmable from Vref to 36 V with two external resistors. These … Read more
