FN6849.1 1. Electrical Chracteristics, Table 1:
a. Added “ISENA” to “Analog input voltages” with value of -3 to
6.5 and removed it’s stand-alone row with value of -1.5 to +30.
b. Removed 120mA row for “MOSFET drive reference”
and”Logic reference”.
2. Electrical Specifications, Table 3:
a. Changed “Logic input bias current” to ““Logic input leakage
current” with condition of “Push-pull logic” with Min of -250nA
and Max of 250nA.
b. Added Note 5 of “Limits established by charcterization and
not production tested” and callouts to the following parameters:
“Soft start delay duration range”, “Soft start ramp duration
range”, “Logic input leakage current”, “Minimum SYNC pulse
width”, “High-side driver peak gate drive current (pull down)”,
“High-side driver pull-up resistance”, “High-side driver pull-
down resistance”, “Low-side driver peak gate drive current (pull-
up)”, “Low-side driver peak gate drive current (pull-down)”,
“Low-side driver pull-up resistance
” , “Low-side driver pull-
down resistance
”, “Switching timing - GH and GL rise and fall”,
“
Power good delay range”, “VSEN undervoltage (and
overvolatge) threshold
” with condition of “Configurable via I2C/
SMBus
”, “VSEN undervoltage/overvoltage fault response
time
” with condition of “Configurable via I2C/SMBus”, “Current
limit protection delay
” with condition of “Configurable via I2C/
SMBus
”, “Thermal protection threshold” with condition of
“
Configurable via I2C/SMBus”.
