LINEAR INTEGRATED CIRCUIT
SWITCH MODE SOLENOID DRIVER
The L294 is a monolithic integrated circuit in an 11-1ead MULTIWATT® package.
It is particularly
suited for solenoid driving,such as hammers and needles in printers and comp hard-copy peripherals.
The switch-mode control of the output current allows electromechanic
ith high working
speed to be driven (switch ON/switch OFF time is very short) and to
r dissipation com-
pared to standard solutions.
Furthermore, the L294 incorporates a diagnostic circuit with lat
function (for instance electromagnet coil in short circuit).
,
The L294 main features are:
high
voltage operation (up to 50V)
high output current capability (up to 4A)
