Description
The L9332 is a monolithic integrated quad low
side driver realized in an advanced Multipower
BCD mixed technology. The device is intended to
drive valves in automotive environment.
The inputs are µP compatible. Particular care has
been taken to protect the device against failures,
to avoid electromagnetic interferences and to offer
extensive real time diagnostic.
