onsemi TPS2399
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 −80 V, and are rated to withstand spikes to −100 V.| Part No. | TPS2399 |
