Inverse load current operation
The device is specified for inverse load current
operation (V
feature is not available during this kind of operation
(I
sic drain source diode is conducting resulting in
considerably increased power dissipation. If the
device is switched on (V
dissipation is decreased to the much lower value
R
Note: Temperature protection during inverse load
current operation is not possible!

Energy stored in load inductance:
While demagnetizing load inductance, the energy
dissipated in PROFET is

Externally adjustable current limit
If the device is conducting, the sense current can be
used to reduce the short circuit current and allow
higher lead inductance (see diagram above). The
device will be turned off, if the threshold voltage of
T2 is reached by I

again, the short circuit current is defined by I
and the device is shut down after t
