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.
