Dual N-Channel MOSFET, 3 A, 4 A, 5 V, 12 V, 8-Pin TSOT23-8L STMicroelectronics STEF512GR

The STMicroelectronics integrated dual electronic fuse, designed to protect circuitry on its output from overcurrent and overvoltage events, in those applications requiring hot swap operation and in-rush current control. It embeds two independent electronic fuses, one for the 5 V rails and one for the 12 V rails. The voltage drop from the main supply to the load is very low during normal operations, due to the very low ON-resistance of the integrated Power FETs. The STEF512GR limits the output current to the predefined safe value, when an overload condition occurs. Start-up time can be adjusted by the user for each e-fuse, via two small soft-start capacitors, connected to the relevant pins.
