Any kind of load. If VGND > VIN - VIN(T+) device stays off

Due to VGND > 0, no VST = low signal available.

For an inductive load current up to the limit defined by EAS

(max. ratings see page 3 and diagram on page 10) each

switch is protected against loss of Vbb.

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.

Any kind of load. In case of IN = high is VOUT ≈ VIN - VIN(T+).

Due to VGND > 0, no VST = low signal available.
