Description

L6ꢀ52 is a device designed to drive two 13x16

matrix ink jet print heads in printer applications.

In order to avoid output activation during the

supply transient, an internal power-up system is

implemented.

The output stage is able to source simultaneously

ꢀ00 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.

As supporting function, L6ꢀ52 is capable of

sensing the head silicon temperature and to

electrically check each nozzle.

The device is also integrating

protection.
