DESCRIPTION

The L6450 is realized in Multipower BCD Tech-

nology which combines isolated DMOS power

transistors with CMOS and Bipolar circuits on the

same IC. By using mixed technology it has been

possible to optimize the logic circuitry and the

power stage to achieve the best possible perform-

ances.

PQFP44

PLCC44

puts are available for the different driver banks.

An internal power-on system is implemented in

order to avoid wrong output commutation during

the supply voltage transients.

Intended to be used in ink jet Printer Applications

as 4 to 28 (2 x 14) or 3 to 28 (4 x 7) lines select-

able decoder/driver, the L6450 device driver has

the advantages of low power CMOS inputs and

logic, with 28 high current and high voltage

DMOS outputs capable of sustaining a maximum

of 40V.

Using a mask option during manufacturing allows

a different decoding.

Control of the energy delivered to the print head

is made by means of a specialcircuitry.

All driver outputs are capable of withdstanding a

contact discharge of ±8KV with the IC biased.

On system power up the output drivers are locked

out using the chip enable function; four enable in-
