Hi Team,
If VDD falls under VUVLOF(Minimum operating voltage after start) how do OUTA/OUTB and SRA/SRB output?
Do these pin output 0V quickly?
My customer wants to know it.

Hi Yaita-san,
As the datasheet said, under fault conditions (UVLO, internal thermal shut down, OVP/OTP, hiccup mode), or when externally disabled, SS pin is pulled down to ground quickly by an internal switch with 2 kΩ on resistance to prepare for re-start. This will shut down all outputs, and new soft start will be triggered after all faults are released.

Hi Oliver-san,
Thank you for your reply.
>This will shut down all outputs, and new soft start will be triggered after all faults are released.
Does "shut down all outputs" mean OUTA/OUTB and SRA/SRB output to be all 0V(GND)?
I believe it but would like to confirm just in case.
Best Regards,
Yaita
