STEL12H24中文资料用于12V、5V和3.3V总线的电子开关数据手册ST规格书

描述 Description

The STEL12H24 is an integrated controlled inrush and overcurrent protection device optimized for power bus architectures.

When connected to a 12 V, 5 V or 3.3 V power rail, it is able to limit the inrush current, detect input voltage faults and short-circuit conditions and signal these events via a Power Good output.

The low RDSON value of the integrated MOSFET guarantees these conditions and low power dissipation during normal operation.

The device is available in a DFN12 leads 3 x 3 mm.
