3 Description
The TPS25942,TPS25944 eFuse Power MUX is acompact,feature rich power management device witha full suite of protection functions.The wide operatingrange allows control of many popular DC busvoltages.Integrated back-to-back FETs providebidirectional current control making the device wellsuited for power muxing and systems with multiplepower sources.
Load,source and device protection are provided with
many programmable features. Thresholds for
undervoltage,overvoltage,overcurrent,dVJdt 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.
The TPS25942,TPS25944 monitor Vaw and Vioun toprovide true reverse blocking from output when Vuny<(Viour)-10 mV).The device can be configured toassign Main/Auxiliary supply priority using the FLTand DMODE pins.
