Description

The L9386 is a monolithic integrated dual low side

driver realized in an advanced Multipower BCD

mixed technology.

It is especially intended to drive valves in

automotive environment. Its inputs are µP

compatible for easy driving. Particular care has

been taken to protect the device against failures,

to avoid electro-magnetic interferences and to

offer extensive real time diagnostic.
