So what do you do? Enter the latching power circuit, often referred to as a “soft” switch. [Chris Chimienti] has recently put together a fascinating video which walks the viewer through five ...

Few realize how close an optical coupler resembles a relay. It is so close, in fact, that one can be wired as a Run-Stop latch circuit. One advantage over the relay is that it may be turned off via a ...

Yet, many PWM controllers do not internally support this latch-off function. Most do, however, have a power-good output and an enable function. The circuit in Figure 1 adds that latch-off capability ...

In this Idea for Design: the Soft-start capacitor's discharge can be used as a trigger for a latch circuit in order to provide latch-off fault response in switching supplies Most switching power ...

For example, a condition known as latch-up has long been a source of frustration for circuit verification engineers. Although the detection of latch-up vulnerability has been heavily researched, it is ...

Latch-up is modeled as a short circuit (low-impedance path) that can occur in an integrated circuit (IC). It may lead to destruction due to over-current resulting from interactions between parasitic ...
