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.
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

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
