Description
L6452 is a device designed to drive two 13x16
matrix ink jet print heads in printer applications.
The output stage is able to source simultaneously
400 mA on each of the 16 power lines (columns)
with a duty cycle of 33% in normal printing and
66% in head pre-heating. On the address lines
(rows), the load is only capacitive (MOS FET
driving capability). The driver can control two print
heads, but only one is active at a time. The
address scanning counter is included and can be
disabled to allow a different scanning scheme.

In order to avoid output activation during the
supply transient, an internal power-up system is
implemented.
As supporting function, L6452 is capable of
sensing the head silicon temperature and to
electrically check each nozzle.
The device is also integrating a thermal
protection.
