CIRCUIT DESCRIPTION

The circuit is designed to drive the direction indicator

flasher relay. Figure 2 shows the typical system configuration

with the external components. It consists of a network (R1,

Pin 6 has to be connected to Pin 2, and the use of capacitor

C is not necessary. The circuit can also be used for other

warning flashers. In this example, when the handbrake is

engaged, it is signaled by the light (L1).

C1) to determine the oscillator frequency, shunt resistor (R )

to detect defective bulbs and short circuits in the system, and

two current limiting resistors (R /R ) to protect the IC against

load dump transients. The circuit can be used either with or

without short circuit detection, and features overvoltage,

defective lamp and short circuit detection.

The lightbulbs L2, L3, L4, L5 are the turn signal indicators

with the dashboard–light L6. When switch S1 is closed, after

a time delay of t (in our example t = 75 ms), the relay will be

actuated. The corresponding lightbulbs (L2, L3 or L4, L5) will

flash at the oscillator frequency, independent of the battery

voltage of 8.0 V to 18 V. The flashing cycle stops and the

circuit is reset to the initial position when switch S1 is open.

Overvoltage Detection

Relay

Senses the battery voltage. When this voltage exceeds

20.2 V (this is the case when two batteries are connected in

series), the relay will be turned off to protect the lightbulbs.

Lightbulb Defect Detector

Senses the current through the shunt resistor R . When one

of the lightbulbs is defective, the failure is indicated by

doubling the flashing frequency.

Short Circuit Detector

Detects excessive current (I > 25 A) flowing in the shunt

(t = 55 ms). In this case, the relay will be turned off. The

circuit is reset by switching S1 to the off position.

Operation with Short Circuit Detection

Pin 6 has to be left open and a capacitor C has to be

connected between Pin 1 and Pin 2.
