ZL6100
The ZL6100 offers the ability to add and drop phases using a
simple command in response to an observed load current
change, enabling the system to continuously optimize
overall efficiency across a wide load range. All phases in a
current share rail are considered active prior to the current
Snapshot? Parameter Capture
The ZL6100 offers a special mechanism that enables the
user to capture parametric data during normal operation or
following a fault. The Snapshot functionality is enabled by
setting bit 1 of MISC_CONFIG to 1.
sharing rail ramp to power-good.
See AN2033 for details on using the Snapshot feature in
Phases can be dropped after power-good is reached. Any
member of the current sharing rail can be dropped. If the
reference device is dropped, the remaining active device with
addition to the parameters supported. The Snapshot feature
enables the user to read status and parameters via a block
read transfer through the SMBus.
the lowest member position will become the new reference.
The SNAPSHOT_CONTROL command enables the user to
Additionally, any change to the number of members of a
current sharing rail will precipitate autonomous phase
distribution within the rail where all active phases realign
their phase position based on their order within the number
of active members.
If the members of a current sharing rail are forced to shut
down due to an observed fault, all members of the rail will
attempt to re-start simultaneously after the fault has cleared.
Monitoring via I 2 C/SMBus
A system controller can monitor a wide variety of different
ZL6100 system parameters through the I 2 C/SMBus
interface. The device can monitor for fault conditions by
monitoring the SALRT pin, which will be pulled low when any
number of pre-configured fault conditions occur.
The device can also be monitored continuously for any
store the snapshot parameters to Flash memory in response
to a pending fault as well as to read the stored data from
Flash memory after a fault has occurred. Table 26 describes
the usage of this command. Automatic writes to Flash
memory following a fault are triggered when any fault
threshold level is exceeded, provided that the specific fault’s
response is to shut down (writing to Flash memory is not
allowed if the device is configured to re-try following the
specific fault condition). It should also be noted that the
device’s V DD voltage must be maintained during the time
when the device is writing the data to Flash memory; a
process that requires between 700μs to 1400μs depending
on whether the data is set up for a block write. Undesirable
results may be observed if the device’s V DD supply drops
below 3.0V during this process.

memory to RAM for immediate access using
SNAPSHOT command.
Writes current SNAPSHOT values to Flash
memory. Only available when device is disabled.
? Temperature of an external device
? Switching frequency
? Duty cycle
The PMBus Host should respond to SALRT as follows:
1. ZL device pulls SALRT Low
2. PMBus Host detects that SALRT is now low, performs
transmission with Alert Response Address to find which
ZL device is pulling SALRT low.
3. PMBus Host talks to the ZL device that has pulled SALRT
low. The actions that the host performs are up to the
System Designer.
If multiple devices are faulting, SALRT will still be low after
doing the above steps and will require transmission with the
Alert Response Address repeatedly until all faults are cleared.
Please refer to Application Note AN2033 for details on how
to monitor specific parameters via the I 2 C/SMBus interface.

In the event that the device experiences a fault and power is
lost, the user can extract the last SNAPSHOT parameters
stored during the fault by writing a 1 to
SNAPSHOT_CONTROL (transfers data from Flash memory
to RAM) and then issuing a SNAPSHOT command (reads
data from RAM via SMBus).
