four power supplies. When either the CONTROL pin
goes active or the OPERATION command is received
(as defined by the ON_OFF_CONFIG command), each
enabled PSENn output goes active (can be active high or
low, as defined in MFR_PSEN_CONFIG) after the associ-
ated delay time programmed in TON_DELAY. The power
supplies can be sequenced on in any order. The output
voltage of each power supply is monitored to ensure
that the supply crosses the undervoltage fault limit (as
configured in VOUT_UV_FAULT_LIMIT) within a pro-
grammable time limit (as configured in TON_MAX_

2. ALTERNATE POWER-DOWN SEQUENCING OPERATION IS TO SHUT OFF ALL SUPPLIES IMMEDIATELY.
3. THE FAULT PIN BEING ASSERTED LOW CAN ALSO CAUSE A POWER-DOWN SEQUENCE TO OCCUR ON GLOBAL CHANNELS.

FAULT_LIMIT). After all enabled supplies are turned on
and above their respective power-good-on levels (as
configured in POWER_GOOD_ON), the PG output
transitions high. The PG output transition can be delayed
with the MFR_PG_DELAY command. When either the
CONTROL pin goes inactive or the OPERATION off
command is received (or the FAULT pin goes low for
GLOBAL channels), the power supplies are sequenced
off. The order in which the supplies are disabled is
determined with the TOFF_DELAY configuration.
Alternatively, all of the power supplies can be switched
off immediately, as configured in the ON_OFF_CONFIG
command or with the OPERATION command.
