Description
General part information
STEF512PUR Series
The STEF512PUR is an integrated dual electronic eFuse, designed to protect circuitry on the output from overcurrent and overvoltage events, in those applications requiring hot swap operation and in-rush current control.
The device embeds two independent electronic fuses, one for the 5 V rails and one for the 12 V rails. Thanks to the very low ON-resistance of the integrated power FETs, the voltage drop from the main supply to the load is very low during normal operation.
The startup time can be adjusted by the user for each eFuse, via two small soft-start capacitors, connected to the relevant pins.
