STEF12 - Electronic fuse

General Description

The STEF12 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): 53 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.
  • Operating junction temp. - 40 °C to 125 °C.
  • Available in DFN10 (3x3 mm) package.
  • UL2367 Recognized - File N. E468771.
