Abnormal voltage conditions
The L9848 survives the following abnormal voltage conditions.
Reverse Battery
applied either directly, or through a load to the drain pins (DRN1-6) with the source pins
(SRC1-6) connected to a load or to ground (cold lamp, solenoid, etc).
Maximum negative transients
that force the drains or sources of the outputs going -20V below the module ground.
Ground offsets
with a maximum of -0.5V to 1.0V between the L9848 ground and any load directly
connected to a chassis ground in the case of high side loads. If driving a low side load there
will not be an offset between the L9848 ground and the load ground. In addition there may
be a maximum ground difference between the L9848 ground and any other module
interfacing with it of -0.5V to 1.0V or ±VAC (10-200Hz).
Loss of ground operation
Any outputs are protected to become active in case of lost ground of the L9848 module with
the supply is still applied.
