Figure 89. ADP5140 Power-Up Sequence

Power-Down Sequence

When the ADP5140 receives the SPI command to power off

(power-down mode (SPI_CMD1)), all power rails turn off at

the same time except for Regulator 2 and Regulator 5.

Regulator 2 and Regulator 5 do not power off until the output

voltage of Regulator 11 is below VMDW, as shown in Figure 90.

If the input voltage on the AVIN pin is below the AVIN UVLO

falling threshold or Regulator 11 is disabled, a fast discharge

switch turns on in Regulator 11. The fast discharge switch is a

2 Ω MOSFET between the OUT11 pin and ground, and the

gate driver comes from the OUT11 pin.
