DESCRIPTION
The TPS2359 dual-slot hot-plug controllers perform
all necessary power interface functions for two
AdvancedMC™ (Advanced Mezzanine Card)
modules.
Two fully integrated 3.3-V channels provide inrush
control, over-current protection, and FET ORing. Two
12-V channels provide the same functions using
external FETs and sense resistors. 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 TPS2359 satisfy the narrow
ATCA™ AdvancedMC™ current limit requirements.
