DESCRIPTION

The VN410 is a monolithic device made using
SGS-THOMSON Vertical Intelligent Power
Technology,integrating all the featuresneeded to
implement a complete automotive flashing
system.

This device has two identical power channels, so
the informations are are specified for only one. R

pins are connected to an external R, C

C

t

networkwhich 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 connectedto 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(directionmode only).

In case of overloading of the power outputs,
built-in-thermalshutdown circuits will reduce duty

,

cycle so as to keep maximum junction

t

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
indicatesthe trailerconnection.

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