STEF12S - Electronic fuse

Description

The STEF12S is an integrated electronic fuse optimized to monitor the 12 V DC power lines.

When connected in series to the main power rail, it is able to precisely detect and react to overcurrent and overvoltage conditions.

Features

  • 15 V typical output overvoltage clamp.
  • Absolute maximum voltage of 25 V.
  • Adjustable current limit.
  • Thermal protection.
  • Input undervoltage lockout.
  • Low inrush current during startup.
  • Integrated 40 mΩ Power FET.
  • En/fault pin.
  • Adjustable slew rate for output voltage.
  • Gate control pin for reverse current blocking FET (DFN10 package).
  • TSOT23-8L and DFN10 (3x3 mm) packages.
  • Latch (STEF12S) or a.
