Figure 14. Correct power up (no fault during power up)

If any of the regulators are powered up before RESETBMCU is out of regulator,

RESETBMCU is not de-asserted and the power up sequence is stopped for up to 2.0

ms. If the fault is cleared and all internal PG signals are asserted within the 2.0 ms timer,

RESETBMCU is de-asserted and the power up sequence continues where it stopped as

shown in Figure 15.
