UAA1041B - AUTOMOTIVE DIRECTION INDICATOR
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, C1) to determine the oscillator frequency, shunt resistor (RS) to detect defective bulbs and short circuits in the syste

UAA1041B 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 t1 (in our example t1 = 75 ms), the relay will be actuated. The corresponding lightbulbs (L2, L3
