Question:

What are TRPG and TPPG of the PG block in S6BP20x family datasheet?

Answer:

The Fig.1 shows the timing chart example of S6BP20x family PG block operation.

This example shows the case of start-up, over voltage protection (OVP) and under voltage protection (UVP).

TPPG is the delay time before the PG pin becomes LOW after VOUT rises to the OVP threshold (PGOVPLH) or falls to the UVP threshold (PGUVPLH)

TRPG is the delay time before the PG pin becomes HIGH after VOUT rises to the UVP threshold voltage (PGUVPLH) or falls to the OVP threshold voltage (PGOVPHL).
