ADM1169
SEQUENCING ENGINE
OVERVIEW
Data Sheet
The ADM1169 SE provides the user with powerful and flexible
control of sequencing. The SE implements a state machine control

of the PDO outputs, with state changes conditional on input
events. SE programs can enable complex control of boards such
as power-up and power-down sequence control, fault event
handling, and interrupt generation on warnings. A watchdog
function that verifies the continued operation of a processor
clock can be integrated into the SE program. The SE can also be
controlled via the SMBus, giving software or firmware control
of the board sequencing.
The SE state machine comprises 63 state cells. Each state has the
following attributes:
? It monitors signals indicating the status of the eight input
pins: VP1 to VP3, VH, and VX1 to VX4.
? It can be entered from any other state.
? Three exit routes move the state machine onto a next state:
sequence detection, fault monitoring, and timeout.

Figure 26. State Cell
The ADM1169 offers up to 63 state definitions. The signals
monitored to indicate the status of the input pins are the
outputs of the SFDs.
WARNINGS
The SE also monitors warnings. These warnings can be generated
when the ADC readings violate their limit register value or when
the secondary voltage monitors on VPx and VH are triggered.
The warnings are OR’ed together and are available as a single
warning input to each of the three blocks that enable exiting
a state.

Delay timers for the sequence and timeout blocks can be
programmed independently and changed with each state
change. The range of timeouts is from 0 ms to 400 ms.
Output condition of the eight PDO pins is defined and
fixed within a state.
It transitions from one state to the next in less than 20 μs,
which is the time needed to download a state definition
from EEPROM to the SE.
It can trigger a write of the black box fault and status
SMBus JUMP (UNCONDITIONAL JUMP)
The SE can be forced to advance to the next state unconditionally.
This enables the user to force the SE to advance. Examples of
the use of this feature include moving to a margining state or
debugging a sequence. The SMBus jump or go-to command
can be seen as another input to sequence and timeout blocks to
provide an exit from each state.
