BLOCK DIAGRAM
MULTIPOWER BCD TECHNOLOGY
DIE
ORDERING NUMBER:
L9377DIE1
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.
