TPS2398, TPS2399 -48 V Hot Swap Controller for Redundant Supply Systems The TPS2398 and TPS2399 integrated circuits are hot swap power managers optimized for use in nominal 48 V systems.

They incorporate an improved circuit breaker response that provides rapid protection from short circuits, while still enabling plug ins to tolerate large transients that can be generated by the sudden switchover to a higher voltage supply.

They are designed for supply voltage ranges up to
