I confirmed the INTVCC_UVLO from the block diagram.
But I can not confirmed value of INTVCC_UVLO.
Let me know if you know this value.
INTVCC UVLO is an input to the OR gate for the PG pin but this signal can't be controlled. What is the reason this is important in your application? INTVCC is the output for the internal…
Can you provide more information about the issue? Could you clarify how is the INTVCC related to the reverse voltage you're seeing?
Have you tried doing the circuit in Figure 6 of the datasheet? This may help in your reverse voltage issue.
