Notes and Conditions
The IBC shuts down, resulting in
both shut down of 3.3 V and 12 V.
Once the substrate temperature
has decreased by 5 ºC, the IBC
turns back on enabling both
voltages
Temperature sensors are on
primary and secondary side.
Once the thresholds have been
exceeded, the 12 V output is
disabled, but the 3.3 V remains.
The 12 V output can only be
enabled by cycling power or
through the I2C interface
provided that the temperature
has decreased below its
hysterisis level. Adjustable
primary and secondary
thresholds are also provided and
can be set lower than the fixed
thresholds. See Application
Note 205.
