  • TPS259827LEVM: TPS259827ONRGET E-fuse Output remains ON when EN/UVLO is at 0V

    Part Number: TPS259827LEVM When in this state, it appears that EN/UVLO is totally ignored when set low (0V). The fuse operation is still correct when in this state - ie over current with lead to the output being turned OFF, and the "indefinite retry"…
