Get to know a number of useful usage of the enable pin of ON Semiconductor’s eFuse. Link here (PDF)
ON Semiconductor electronic fuses (eFuses) are analog integrated circuits that are used to protect circuits operating from 3.3, 5, or 12 V DC supplies. They have numerous protection functionalities such as overvoltage clamping, current limiting, thermal shutdown, and a controlled output voltage slew rate. They are available in thermal latching or thermal auto-retry configurations.
A key feature of the eFuse family is the enable pin. This application note describes the features of the enable pin and provides guidance to ensure its proper use. The enable pin of any eFuse may be left floating if the application does not require that it be controlled and does not require thermal fault notification.
