Questions about TPS26631 in the TPS2663x series.
Inrush current occurs when [External power supply input voltage is suddenly increased].
The inrush current causes the overcurrent protection (OCP) to operate, which stops the e-fuse.
If overcurrent protection is set with ROL<2kΩ, inrush current < overcurrent protection, so shutdown will not occur.
However, setting ROL<2kΩ is not allowed on the datasheet.
Can you please suggest another countermeasure?
e.g., when a re-inrush current occurs, use an external circuit or other countermeasure to charge the circuit by [dvdt], etc.
Best reguard.
