Application Information

NOTES: 1. In the above application, the MC33193 is compatible with the UAA1041 and UAA1041B except

for the shunt resistor value (RS = 20 mΩ).

2. The flashing cycle is started by the closing of switch S1.

3. The position of switch S1 is sensed across resistor R2 and RLamp by the input, Pin 8.
