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

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

limits.

connected to an external green LED which
