[TPS659037] Power-on request

Hi TI Experts,

Please let me confirm the following question.

[Question]

Now my customer thought to achieve that the POWERHOLD pin is pulled up to LDOVRTC_OUT and will generate the ON REQUEST by PWRON button.

However ,I think that the PWERON button does not work because the POWERHOLD pin will be High. The LDOVRTC_OUT is always on after supply the power for PMIC. And the POWERHOLD pin watch the power level. If there is High level on POWERHOLD pin, the PMIC start the ON REQUEST. This is why they get hard to achieve by this hardware. Is my understanding correct?

Or the POWER ON pin can generate the ON REQUEST even though the POWERHOLD pin is HIGH status?

Best regards.
