Additional Infomation About Product

STEF033 Electronic fuse for 3.3 V line Datasheet - production data Description The STEF033 is an integrated electronic fuse optimized for monitoring output current and the input voltage. Connected in series to the 3.3 V rail, it is able to protect the electronic circuitry on its output from overcurrent and overvoltage. The STEF033 has controlled delay and turn-on time. DFN10 (3 x 3 mm) Flip Chip 9 When an overload condition occurs, the device 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 Features short-circuit is present on the board, when the power is re-applied the eFuse initially limits the Continuous current typ.: 3.6 A (DFN), 2.5 A output current to a safe value and then goes (Flip Chip) again into the open state. The voltage clamping N-channel on resistance (typ): 40 m (DFN), circuit prevents the output voltage from exceeding 25 m (Flip Chip) a fixed value, if the input voltage goes beyond this threshold. The device is equipped with a thermal Enable/Fault functions protection circuit. Intervention of thermal Output clamp voltage (typ): 4.5 V protection is signaled to the board-monitoring Undervoltage lockout circuits through an appropriate signal on the Fault pin. Unlike mechanical fuses, which must be Short-circuit limit physically replaced after a single event, the eFuse Overload current limit does not degrade in its performances following Controlled output voltage ramp short-circuit/thermal protection intervention and is reset either by re-cycling the supply voltage or Thermal latch (typ): 160 C using the appropriate Enable pin. The STEF033 Uses tiny capacitors is also available in an auto-retry version in case Latching and auto-retry versions of thermal fault it automatically attempts to re- apply power to the load when the die temperature Operative junction temp. - 40 C to 125 C returns to a safe value.
