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. 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 BLOCK DIAGRAM March 1998 1/11 VN410 ABSOLUTE MAXIMUM RATING Symb ol -Vbat V BR( DSS) V p1 I p1 I Out V gnd IR V esd P tot Tj T s tg Parameter Reverse Supply Voltage Drain-Source Breakdown Voltage Breakdown Voltage in Pad : LEDEM (V bat < 15V) (V bat > 15V) Value -12 60 (Internally clamped) V bat 15 +/- 10 -10/+100 15 0.4 -15 2000 Internally Limited Internally Limited -55 to 150 Unit V V V V mA mA A V A V W o C o C Breakdown Current in Pad : RT, CT , ROL LDIR,RDIR Maximum DC Load Current Voltage Drop Between ground connections (see note 1) Reverse Output Current Electrostatic Discharge (R = 1.5 k, C = 100 pF) o Power Dissipation at T c 25 C Junction Operating Temperature Storage Temperature 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.

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. 6/11 VN410 FIGURE 2: Switching Waveforms 7/11 VN410 FIGURE 3: Buzzer Functionality TYPICAL APPLICATION DIAGRAM 8/11 VN410 MULTIWATT-15 MECHANICAL DATA DIM.
