STEF12E - Electronic fuse

General Description

The STEF12E is an integrated electronic fuse optimized for monitoring output current and input voltage.

Connected in series to a 12 V rail, it is capable of protecting the electronic circuitry on its output from overcurrent and overvoltage.

The device has a controlled delay and turn-on time.

Key Features

  • Continuous current typ. 3.6 A.
  • N-channel on-resistance typ. 45 mΩ.
  • Enable/fault functions.
  • Output clamp voltage typ. 15 V.
  • Undervoltage lockout.
  • Short-circuit limit.
  • Overload current limit.
  • Controlled output voltage ramp.
  • Thermal latch typ. 165 °C.
  • Uses tiny capacitors.
  • Operating junction temp. -40 °C to 125 °C.
  • Available in DFN10 (3x3 mm) package.
  • UL2367 Recognized - File N. E46.
