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