The device provides integrated protection functions. These are designed to prevent IC destruction under fault
conditions described in the data sheet. Fault conditions are considered as “outside” normal operating range.
Protection functions are not to be used for continuous or repetitive operation, with the exception of the current
limitation
the IS pin as described in the paragraph
and
In the following the protection functions are listed in order of their priority. Overvoltage lock out overrides all other
error modes.
6.3.1
To assure a high immunity against overvoltages (e.g. load dump conditions) the device shuts both lowside
MOSFETs off and turns both highside MOSFET on, if the supply voltage
protection level V
decreases below the switch-on voltage
highside during over voltage.
