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. Rt,
Ct 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.

FUNCTIONAL DESCRIPTION
- NORMAL OPERATION
T he right or left channel is activated by the corresponding position of the direction indicator through the
direction input pins. Each time an output (or both) is activated, the buzzer is also activated through the
BUZZ pin at the double frequency than the output(s). In emergency case, if the emergency button is
activated the two channels are turned on. At the same time the emergency red LED is flashing. An
anti-theft alarm can be connected to the AL pin, in that condition if the anti-theft alarm is used the two
channels are activated.
- UNDER-VOLTAGE OR OVER-VOLTAGE CONDITION
In case the device detects an undervoltage or an overvoltage condition the activated channel(s) are
automatically switched off whatever the input commands (LDIR, RDIR, AL, EM)
- TRAILER OPERATION
T he trailer detection is achieved with the ROL external resistor. In that case the green trailer LED is
flashing through the pin LEDT in synchronism with the outputs.
- LOW LOAD CONDITION
The low load detection is achieved with the ROL external resistor connected between RO L pin and RT pin.
If a low load condition has been detected the output flashing frequency on the guilty channel and the
buzzer frequency will be double (in direction mode only) .
- POWER LIMITATION CONDITION
In case of overloading of the power outputs the duty cycle is reduced internally by the device itself so as to
keep maximum junction temperature within safe limits.
- CHIP GROUND DISCONNECTION
If GND pin is disconnected, the device will switch off provided V bat does not exceed 18V.
