DescriptionThe TPS25942, TPS25944 eFuse Power MUX is a compact, featurerich power management device with a full suite of protection functions. The wide operating rangeallows control of many popular DC bus voltages. Integrated back-to-back FETs provide bidirectionalcurrent control making the device well suited for power muxing and systems with multiple powersources.
Load, source and device protection are provided with many programmable features.Thresholds for undervoltage, overvoltage, overcurrent, dVo/dt ramp rate,power good, and in-rush current protection are all programmable to suit specific systemrequirements. For system status monitoring and downstream load control, the device provides PGOOD,FLT and DMODEpins.
