Additional Infomation About Product

STEF12E Datasheet Electronic fuse for 12 V line Features Continuous current typ. 3.6 A N-channel on-resistance typ. 45 m Enable/fault functions DFN10 (3x3 mm) 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 Applications Hard disk drives Solid state drives (SSD) Hard disk and SSD arrays Set-top boxes DVD and Blu-ray disc drivers Maturity status link Description STEF12E The STEF12E is an integrated electronic fuse optimized for monitoring output current Device summary 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 Order code STEF12EPUR controlled delay and turn-on time. When an overload condition occurs, the STEF12E Package DFN10 (3x3 mm) 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 Packing Tape and reel 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 signalled to the board monitoring circuits through a signal on the Fault pin. Unlike the mechanical fuses, which must be physically replaced after a single event, the Efuse does not degrade in its performance after short-circuit/thermal protection interventions and it is reset either by recycling the supply voltage or using the Enable pin. The companion chip for the 5 V power rails is also available with part number STEF05.
