ORDERING NUMBER: L9386MD
DESCRIPTION
The L9386MD is a monolithic integrated dual low
side driver realized in an advanced MultipowerBCD 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.
