The TPS2474x is an integrated ORing and Hot Swap controller for 2.5 V to 18 V systems. It's precise and programmable protection settings aid in the design of high power, high availability systems where isolating faults is critical.
Programmable current limit, fast shut down, and fault timer protect the load and supply during fault conditions such as a hot - short. The fast shutdown threshold and response time can be tuned to ensure a fast response to real faults, while avoiding nuisance trips. Programmable SOA (Safe Operating Area) protection and the inrush timer keep the MOSFET safe under all operating conditions. After asserting a power good, TPS2474x runs the fault timer during over-current events, but doesn’t current limit. It shuts down after the fault timer expires. Two independent timers (inrush/fault) allow the user to customize protection based on system requirements. The ORing function of the TPS2474x allows the user to program the reverse voltage threshold and response time to aid in the design of redundant power supply systems.
