GND disconnect
Any kind of load. In case of IN = high is V
Due to V
V
load
For inductive load currents up to the limits defined by Z
(max. ratings and diagram on page 11) each switch is
protected against loss of V bb .
Consider at your PCB layout that in the case of Vbb dis-
connection with energized inductive load all the load current
flows through the GND connection.

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