DESCRIPTION
The L9377 is a monolithic integrated dual low
side driver realized in an advanced Multipower-
BLOCK DIAGRAM
MULTIPOWER BCD TECHNOLOGY
DIE
ORDERING NUMBER: L9377DIE1
BCD mixed technology. It is especially intended
to drive valves in automotive environment. Its in-
puts are µP compatible for easy driving. Particular
care has been taken to protect the device
against failures, to avoid electro-magnetic inter-
ferences and to offer extensive real time diag-
nostic.
