Independent 12-V Current Limit and Fast Trip
12-V FET ORing for MicroTCA™
Internal 3.3-V Current Limit
Two fully integrated 3.3-V channels provide inrush
control, current limiting, and overload protection. The
two 12-V channels use an external FET to provide
the same functions, along with ORing control circuits
that allow an external FET to prevent reverse current
flow. The 3.3-V current limits are factory set to
AdvancedMC™ compliant levels and the 12-V current
limits are programmed using external sense resistors.
The accurate current sense comparators of the
TPS2358 satisfy the narrow ATCA AdvancedMC™
current limit requirements.
