TPS2459EVM-TPS2459 I2C Hot Swap/ORing Controller Evaluation Module

The Full-Featured AdvancedMC™ Slot Controller Evaluation Module (EVM) is a PCB platform for users to learn about the features and operation of the TPS2459 integrated circuit (IC) from Texas Instruments (TI). The TPS2459 Full Featured AdvancedMC™ Slot Controller manages a single 12 V and single 3.3-V power rails, and features inrush and fault current limiting, FET OR’ing, input UVLO protection, logic-level enable inputs and an I2C interface. Current control on the 12 V rail has a high degree of programmability, including independent current limit and fast trip thresholds. System level timing and other control parameters are accessed via the I2C interface, along with readback of FET and output rail status. In addition, current sense and pass and block FET’s for the 3.3 V channel are fully integrated into the device. Power management applications based on the TPS2459 are easily configured to meet the requirements for 12 V and 3.3 V control of Advanced Mezzanine Card (AdvancedMC™) modules. Each device incorporated onto a Carrier Card provides full power control for an AdvancedMC™ slot according to the requirements of the Advanced Telecommunications Computing Architecture (ATCA™) specification, PICMG 3.0. In addition, the input supply FET OR’ing control for the 12 V rail facilitates efficient redundant supply implementations in Micro Telecommunications Computing Architecture (MicroTCA™) systems.
