General Description

The TPS2458 AdvancedMC™ slot controller is fully compliant with the AdvancedMC™ Standard and provides the required accuracy to meet the demands of an AdvancedMC™ (Advanced Mezzanine Card) module.

The TPS2458 is an extremely flexible solution that protects both the power supply and the load by limiting the maximum current into the load and shutting off in case of a fault.

If a severe fault occurs the current shuts off immediately.
