STEF05S - Electronic fuse

General Description

The STEF05S is an integrated electronic fuse optimized for monitoring the 5 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.

Key Features

  • 5.7 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.
  • TSOT23-8L package.
  • Latch (STEF05S) or auto-retry (STEF05SA) versions.
