Other Parts Discussed in Thread: TPS73801
I'm guessing a wrong vertical axis labelling for figure 11 and 12, which makes EN-pin threshold voltage spec confusing.
By comparing TPS73801 revC and TPS73801-SEP revA datasheet,
it looks like vertical axis for figure 11 and 12 of TPS73801-SEP datasheet should be "EN threshold Voltage" (V) rather than "SHDN Input Current (μA)"
By the way, vertical axis scale of 0.1V would be easier to read.
Can you confirm ?
