TPS2458EVM

Power Management IC Development Tools TPS2458 ATCA AdvMC Cntlr w/I2C Eval Mod

The is a TPS2458 based hot swap/ORing controller evaluation module, which is a PCB platform for users to learn about the features and operation of the TPS2458 integrated circuit. The TPS2458 ATCA AdvancedMC controller IC manages a 12V and a 3.3V power rail and features inrush and fault current limiting, FET OR"ing, input UVLO protection and logic level enable inputs. Current control on the 12V rail has a high degree of programmability, including independent current limit and fast trip thresholds. Overcurrent fault timing is managed with user programmable shut down delays, and each of the two power channels has dedicated fault and power good reporting outputs. In addition, current sense and pass and block FET"s for the 3.3V channel is fully integrated into the device. Power management applications based on the TPS2458 are easily configured to meet the requirements for 12V and 3.3V control of advanced Mezzanine Card modules.
