TPS2350-12-V to -80-V hot swap controller with Oring | Evaluation Boards | 8 | Active | The TPS2350 is a hot swap power manager optimized for replacing OR-ing diodes in redundant power –48-V systems. The TPS2350 operates with supply voltages from –12 V to –80 V, and withstands spikes to –100 V.
The TPS2350 uses two power FETs as low voltage drop diodes to efficiently select between two redundant power supplies. This minimizes system power dissipation and also minimizes voltage drop through the power management chain.
The TPS2350 also uses a third power FET to provide load current slew rate control and peak current limiting that is programmed by one resistor and one capacitor. The device also provides a power good output to enable down-stream power converters and a fault output to indicate load problems.

TPS23525-10-V to -80-V hot swap controller with dual current limit and dual Oring | Evaluation and Demonstration Boards and Kits | 3 | Active | The TPS23525 is an integrated hot swap and dual OR-ing controller that enables high power telecom systems to comply with stringent transient requirements. The 200-V absolute maximum rating makes it easier to survive lightning surge tests (IEC61000-4-5). The soft start cap disconnect allows for the use of smaller hot swap FETs by limiting the inrush current, without hurting the transient response. The 400-µA sourcing current allows fast recovery, which helps to avoid system resets during lightning surge tests. The dual current limit makes it easier to pass brown outs and input steps such as required by the ATIS 0600315.2013. Finally, it offers accurate undervoltage and overvoltage protection with programmable thresholds and hysteresis.
The TPS23525 integrates a dual OR-ing controller, making it ideal for –48-V systems fed by two redundant supplies.

TPS23598.5-V to 15-V dual channel hot swap controller with Oring and Ad-VancedMC compliance | Integrated Circuits (ICs) | 3 | Active | The TPS2359 dual-slot hot-plug controllers perform all necessary power interface functions for two AdvancedMC™ (Advanced Mezzanine Card) modules.
Two fully integrated 3.3-V channels provide inrush control, over-current protection, and FET ORing. Two 12-V channels provide the same functions using external FETs and sense resistors. The 3.3-V current limits are factory set to AdvancedMC™ compliant levels and the 12-V current limits are programmed using external sense resistors. The accurate current sense comparators of the TPS2359 satisfy the narrow ATCA™ AdvancedMC™ current limit requirements.
