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
μ
P compatible. Particular care has
been taken to protect the device against failures, to
avoid electromagnetic interferences and to offer ex-
tensive real time diagnostic.
