Typical Application

C
Connecting a capacitor between the C
output voltage ramp up time.
Given the desired time interval t during which the output voltage goes from zero to his
maximum value, the capacitance to be added on C
following theoretical formula:
Where C
The addition of an external C
between the Enable signal going high and the start of the V
The contribution of the external capacitor to this time interval can be extimated by using the
following theoretical formula:
Enable-fault pin
The Enable/Fault pin has the dual function of controlling the output of the device and, at the
same time , of providing information about the device status to the application.
When it is used as a standard Enable pin, it should be connected to an external open-drain
or open-collector device. In this case, when it is pulled at low logic level, it will turn the output
of the E-Fuse off.
