What is Desaturation Protection (DESAT) for Driver Chips?

What is Desaturation Protection (DESAT) for Driver Chips?

Motivation:The short-circuit protection methods for power devices can be divided into two main categories: detecting short-circuit current and detecting voltage drop. The current detection method is commonly done through a Sense FET or a shunt resistor, while voltage detection is referred to as desaturation protection. Most power modules do not have an integrated Sense FET, … Read more
