FN6859.1 Added Note 15: “Nominal capacitance of logic pins is 5pF”. Added Note 15 callouts to Logic Output Low, VOL and Logic

Output High, VOH parameters.

Changed “Logic Input Bias Current” parameter to “Logic Input Leakage Current”. Changed Logic Input Leakage Current

Min from -10µA to -250nA and Max from 10µA to 250nA.

Removed “MGN Input Bias Current” line from table.

Changed “Power Good VOUT Low Threshold” parameter to “Power Good VOUT Threshold” and removed “Power Good VOUT

High Threshold” line from table.

Page 10:

Removed 2 paragraphs as follows:

“The ZL2008 can be configured by simply connecting its pins according to the tables provided in the following sections…

I2C/SMBus interface using an available computer and the included USB cable.”

“Application notes and … local Zilker Labs sales office to order an evaluation kit”

Throughout: Changed all referenced Zilker App note numbers to newly assigned Intersil numbers (e.g. AN33 -> AN2033)

“Current Limit Threshold Selection” on page 21. In paragraph below Figure 16, changed “The current sensing method can

be selected via the I2C/SMBus interface.” to “The current sensing method can be selected using the CFG2 pin as shown

in Tables 26 and 28 or via the I2C/SMBus interface.” In 3rd paragraph below Figure 16, changed “This is to avoid taking

a reading just after a current load step” to “This is to avoid taking a reading just after a switching transition”. Added “Note

that IOUT_CAL_GAIN is set to 2m

 by default.” to end of last paragraph.

Added “(Voltage seen on 2m

)” to Tables 14 and 15 captions on page 21.

Replaced Table 25. Phase Offset Pin-strap Settings on page 30 (changed “CFG2 Pin” column to “RCFG2” and added

“Current Sense” column).

Table 26. Phase Offset Resistor Settings on page 30. Added “Current Sense” column and RCFG2 rows from 42.2k through

162k

 and corresponding Phase Offset rows.

On page 30: 2nd column, 1st paragraph, changed “The phase offset of (multi-phase) current sharing devices is

automatically set to a value between 0° and 337.5° in 22.5° increments as follows: Phase Offset = SMBus Address[4:0]

–Current Share Position * 22.5°” to “The phase offset of a current sharing group is automatically set to a value between

0° and 337.5° in 22.5° increments as follows: Phase Offset = (SMBus Address[4:0] –Current Share Position) * 22.5°”

Added “The phase of the individual members in a group are spread evenly from the phase offset of the group.”

Table 28. Current Share Position Settings on page 33. Added “Current Sense” column. Added RCFG2 rows from 42.2k

through 82.5k

 and corresponding Current Share Position rows.

Removed former Table 35. Snapshot Parameters

“Snapshot Parameter Capture” on page 35. Added “See AN2033 for details on using the Snapshot in addition to the

parameters supported.” to 2nd paragraph

On page 4, corrected:

“Analog Input Voltages for ISENA Pin. . . . . . . . . . . . . . . . . . . . .1.5V to 30V”

to:

“Analog Input Voltages for ISENA Pin. . . . . . . . . . . . . . . . . . . .-1.5V to 6.5V”

On page 21, Table 14, added “DCR VLIM (mV)” column. Renamed “Threshold Voltage” column to “RDS VLIM”

On page 22, Table 15, added “DCR VLIM (mV)” column. Renamed “VLIM” column to “RDS VLIM”

On page 21, in second column, first paragraph, changed “Note that IOUT_CAL_GAIN is set to 2m

 by default.” to “By

default, the IOUT_CAL_GAIN is set to 1m

 for DCR mode and 2m for RDS mode.”

In Table 14 on page 21, removed “ (Voltage seen on 2m

)” from caption

In Table 15 on page 22, removed “(Voltage seen on 2m

)” from caption

October 2009

“Power Good” on page 16, changed 2nd sentence from “...if the output is within -10%/+15% of the target voltage.” to “...if

the output is within -10% of the target voltage.”

Replaced last paragraph in “Power Good” section.

“Fault Spreading” on page 31, added “or in sequencing order” to last sentence.

Change marketing part number to ZL2008ALBFT to note firmware revision.
