12-V/3.3-V Hot Swap and ORing Controller with Load Current Monitor for AdvancedMC™

FEATURES

DESCRIPTION

•

ATCA AdvancedMC™ Compliant

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.

•

Full Power Control for an AdvancedMC™

Module

Programmable 12-V Current Limit and Fast

Trip

The TPS2458 is an extremely flexible solution that

protects both the power supply and the load by

limiting the maximum current into the load, shutting

off in case of a fault. If a severe fault occurs the

current shuts off immediately.

•

Optional 12-V ORing Control for MicroTCA™

Internal 3.3-V Current Limit

Programmable Shunt Gain

Interlock Requires 3.3-V Output Prior to 12 V

12-V and 3-V Power Good and Fault Outputs

Load Current Monitor

Optional ORing support is inherent in the architecture

and can be used in MicroTCA™, or other applications

requiring ORing support.

32-Pin PQFN Package

The 3.3-V management channel is internal and

requires only one external resistor for load monitoring

and one external capacitor to set fault time. To

comply with the AdvancedMC™ requirements, the

12-V output is disabled unless the 3.3-V Power Good

signal is asserted. Load current monitors are provided

for both the 12 V and 3.3 V channels. Status outputs

include Power Good and Fault indicators for each

channel. The TPS2458 is in a 32-pin PQFN package.
