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.

Application
• Bus protection
• Hot-swap and peripheral port protection
• Telecom, Networking and Industrial equipment
• Servers and Gateways
