DESCRIPTION
L6452 is a device designed to drive two 13x16
matrixink jet printheadsin printerapplications.
The output stageis able to sourcesimultaneously
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 onlycapacitive (MOS FET driv-
ing capability). The driver can control two print-
heads, but only one is active at a time. The ad-
dress scanning counter is included and can be
disabled to allow a differentscanning scheme.

In order to avoid output activation during the sup-
ply transient, an internal power-up system is im-
plemented.
As supportingfunction, L6452 is capable of sens-
ing the head silicon temperature and to electri-
cally check each nozzle.
The device is also integrating a thermal protec-
tion.
