Figure 24. Activation Command Using the EN Pin
When activated through the EN pin, the sequencer is affected
only by the I2C commands that set or clear the regulator power
good masking bits: Bit 3 (BK1_XSHTDN), Bit 2 (BK2_XSHTDN),
and Bit 1 (LDO_XSHTDN) in the OPERATIONAL_CONTROL
register (Address 0x04). See the Default Power-On Sequence with
EN Pin section for more information. The sequence order of the
regulators is factory programmed through fuses, but the delays
between the regulators (tREG1, tREG2, and tREG3) are fixed and cannot
be changed.
The EN_ALL bit (Bit 4) in the REG_CONTROL_STATUS regi-ster
(Address 0x03) has the same functionality as the EN pin. The
sequencer has an antiglitch function that allows it to ignore supply
voltage dip if glitch time is less than 50 μs (see Figure 25).
