The load inrush current is limited by the TPS2331. The system also protected by TPS2331 from a load fault in its traditional tole as a hot-swap controller. However, the TPS231 must protect the system against a power supply module fault in an OR-ing circuit. The TPS2331 is required by the former role to trip if excessive current flows into the […]

The TPS2390 and TPS2391 integrated circuits are hot swap power managers. These devices are optimized for use in nominal -48-V system. These devices are build with supply voltages ranges up to -80 V. These devices also rated to withstand spikes to -100 V. They can be used to enable live insertion of plug-in cards and modules in powered systems in […]

The HYM1422 is an integrated 2.7V to 12V hot swap controller. This device allows a board to be safely inserted and removed from live backplanes. This is achieved using a pass FET with a current control loop that using a sense resistor, we can monitor the input current. The board supply voltage can be ramped up at a programmable rate […]

This is Positive Low Voltage Hot Swap Controller circuit with Power Limiter. This circuit gives intelligent control of the power supply voltage to the load during removal and insertion of circuit cards from “hot” power sources or a live system backplane. This circuit uses The LM25069 that gives in-rush current control to limit system voltage transients and droop. This circuit […]

This is Positive High-Voltage Hot Swap Controller circuit with Power Limiter. This circuit uses the TPS2491 or TPS2490 because both of them have some advantages. The advantages of the TPS2491 and TPS2490 are positive high voltage, easy-to-use and has 10-pin Hot Swap Power Manager™ devices. 10-pin Hot Swap Power Manager™ devices will ensure the safety in driving an external N-channel […]
