DESCRIPTION
3.3-V and 12-V FET ORing Control for
MicroTCA
The
TPS2459
hot-plug
controller
performs
all
necessary
power
interface
functions
for
an
12-V Output Shuts Off If 3.3-V Output Shuts
AdvancedMC (Advanced Mezzanine Card). A fully
Off
integrated 3.3-V channel provides inrush control,
Internal 3.3-V Current Limit and ORing
over-current protection, and FET ORing. A 12-V
I2C Power Good and Fault Reporting
channel provides the same functions using external
FETs and sense resistors. The 3.3-V current limit is
I2C Programmable Fault Times and Limits
factory set to AdvancedMC compliant levels while
FET Status Bits for 3.3-V and 12-V Channels
the 12-V current limit is programmed using external
Load Current Monitors for 12-V and 3.3-V
sense
resistors.
The
accurate
current
sense
comparators of the TPS2459 satisfy the narrow
32-Pin QFN Package
ATCA AdvancedMC current limit requirements.
