Product Overview

The STEF05PUR is an integrated Electronic Fuse optimized for monitoring output current and input voltage. Connected in series to a 5V 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. When an overload condition occurs, the STEF05 limits the output current to a predefined safe value. If the anomalous overload condition persists, it goes into an open state, disconnecting the load from the power supply. If a continuous short-circuit is present on the board, when power is re-applied the E-fuse initially limits the output current to a safe value and then again goes into an open state. The device is equipped with a thermal protection circuit. The intervention of the thermal protection is signaled to the board monitoring circuits through a signal on the Fault pin.
  • Enable/fault functions
  • Undervoltage lockout
  • Short-circuit limit
  • Overload current limit
  • Controlled output voltage ramp
  • Uses tiny capacitors
