TPS2458 ATCA™ AdvancedMC™ Controller With I2C Evaluation Module (Rev. A)

The AdvancedMC™ Controller Evaluation Module (EVM) is a PCB platform for users to learn about the features and operation of the TPS2458 integrated circuit (IC) from Texas Instruments (TI). The TPS2458 ATCA™ AdvancedMC™ Controller IC manages a 12-V and a 3.3-V power rail and features inrush and fault current limiting, FET OR’ing, input UVLO protection and logic-level enable inputs. Current control on the 12-V 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 3.3-V channel is fully integrated into the device.
