For an inductive load current up to the limit defined by E
AS
(max. ratings see page 3 and diagram on page 10) 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 the whole load
current flows through the GND connection.
