12-V/3.3-V Hot Swap and ORing Controller with Load Current Monitor for AdvancedMC
2
ATCA AdvancedMC Compliant
The TPS2458 AdvancedMC slot controller is fully
compliant with the AdvancedMC Standard and
Full Power Control for an AdvancedMC
provides the required accuracy to meet the demands
Module
of an AdvancedMC (Advanced Mezzanine Card)
Programmable 12-V Current Limit and Fast
module.
Trip
The TPS2458 is an extremely flexible solution that
Optional 12-V ORing Control for MicroTCA
protects both the power supply and the load by
Internal 3.3-V Current Limit
limiting the maximum current into the load, shutting
Programmable Shunt Gain
off in case of a fault. If a severe fault occurs the
current shuts off immediately.
Interlock Requires 3.3-V Output Prior to 12 V
Optional ORing support is inherent in the architecture
12-V and 3-V Power Good and Fault Outputs
and can be used in MicroTCA, or other applications
Load Current Monitor
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
ATCA Carrier Boards
comply with the AdvancedMC requirements, the
MicroTCAPower Modules
12-V output is disabled unless the 3.3-V Power Good
AdvancedMC Slots
signal is asserted. Load current monitors are provided
for both the 12 V and 3.3 V channels. Status outputs
Systems Using 12 V and 3.3 V
include Power Good and Fault indicators for each
Base Stations
channel. The TPS2458 is in a 32-pin PQFN package.
