STEF512GR Datasheet Dual Electronic Fuse

Manufacturer: STMicroelectronics

Overview: STEF512GR Datasheet Dual electronic fuse for 5 V and 12 V rails Maturity status link.

General Description

The STEF512GR is an 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.

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 operations.

Key Features

  • 5 V and 12 V channels into one chip.
  • 25 V absolute maximum input voltage.
  • Precise output over voltage clamp.
  • Fixed current limit: 3 A on 5 V, 4 A on 12 V.
  • Latched-off thermal protection.
  • Input undervoltage lockout.
  • Adjustable output voltage slew-rate for each channel.
  • Integrated 40 mΩ Power FETs.
  • SAS disable pin.
  • TSOT23-8L package.
