DESCRIPTION
The VN410 is a monolithic device made using
SGS-THOMSON
Vertical
Intelligent
Power
Technology, integrating all the features needed to
implement
a
complete
automotive
flashing
system.
This device has two identical power channels, so
the informations are are specified for only one. R
t
,
C
t
pins are connected to an external R, C
network which fixes the flashing frequency. LDIR,
RDIR direction inputs activate the corresponding
output (or none). EM inputs turns on both power
outputs for emergency flashing, which is reflected
by flashing red LED connected to LEDEM output.
AL input can be connected to an anti-theft alarm
system, making both power outputs flashing. In
case of low load (burned lamp) buzzer frequency
and outputs flashing will double, thus indicating a
fault condition (direction mode only).
In case of overloading of the power outputs,
built-in-thermal shutdown circuits will reduce duty
cycle
so
as
to
keep
maximum
junction
temperature within
safe
limits.
Rol
pin
is
connected to an external resistor to detect a
burned lamp and a trailer connection. LEDT is
connected to an external green LED which
indicates the trailer connection.

Note 1: In case the voltage drops beetween ground connection exceed 0.4V, extenal resistors in series with EM pin and AL pin are needed
(if these pins are used) to prevent damages to the device. The value of these resistors is 100
