TPS7H1301EVM-CVAL EN Independently Driven LOW Figure 3-5 EN Independently Driven LOW.
TPS7H1301EVM-CVAL EN Tied to Falling VIN via Resistor Divider Figure 3-6 EN Tied to Falling VIN via Resistor Divider.

CPOUT and EN follow the falling VIN voltage until EN reaches the turn-off threshold and disables CPOUT and VOUT.

TPS7H1301EVM-CVAL Power Good De-assert - EN Tied to Falling VIN via Resistor Divider Figure 3-8 Power Good De-assert - EN Tied to Falling VIN via Resistor Divider. Because VIN is falling in this waveform, the PG output can be observed briefly in an undefined state while VIN is below VIN_MIN_PG (0.8V nominal).
