The TPS25944LRVCT is an eFuse Power Multiplexer, rich power management device with a full suite of protection functions. The wide operating range allows control of many popular DC bus voltages. Integrated back-to-back FETs provide bidirectional current control making the device well suited for power muxing and systems with multiple power sources. 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 system requirements. For system status monitoring and downstream load control, the device provides PGOOD, FLT and precise current monitor output.
