DESCRIPTION
The L9349 is a monolithic integrated quad low side
driver realized in an advanced MultipowerBCD mixed
technology. The device is intended to drive valves in
automotive environment.
The inputs are
µP compatible. Particular care has
been taken to protect the device against failures, to
avoid electromagnetic interferences and to offer ex-
tensive real time diagnostic.
