In this two-stage ESD protection circuit, there are two transistors that help short the positive high-voltage ESD transient to ground, while the diodes take care of negative excursions.

For power-supply controllers with an external soft-start pin, however, a simple circuit can be added to convert its non-latching fault protection into one with latched protection.

A Simple Over-Voltage Protection Circuit for LED Drivers This boost circuit implements current mode control and senses the LED current via resistor R14. The output voltage is boosted to just over 30V ...

Several key technology trends are changing electrostatic discharge (ESD) protection requirements. High-speed interfaces, for example, affect signal integrity, and shrinking geometries make ...

My introduction to circuit protection came at the tender age of eight. Being a curious lad with an inventive – and apparently self-destructive – bent, I decided to make my mother a lamp.

[Mark Rehorst] tells us about a tragic incident involving an untimely demise of $200 worth of motor driving hardware, and shares a simple circuit so that we can prevent such tragedies in the future… ...
