TECHNICAL DATA
Automotive Direction Indicator
IL33193A
The IL33193A is a new generation industry standard UAA1041 “Flasher”.
It has been developed for enhanced EMI sensitivity, system reliability, and
improved wiring simplification. The IL33193A is pin compatible with the
UAA1041 and UAA1041B in the standard application configuration as shown
in Figure 9, without lamp short circuit detection and using a 20 mshunt
resistor. The IL33193A has a standby mode of operation requiring very low
standby supply current and can be directly connected to the vehicle’s battery. It
includes an RF filter on the Fault detection pin (Pin 7) for EMI purposes. Fault
detection thresholds are reduced relative to those of the UAA1041, allowing a
lower shunt resistance value (20 m) to be used.
• Pin Compatible with the UAA1041
• Defective Lamp Detection Threshold
• RF Filter for EMI Purposes
• Load Dump Protection
• Double Battery Capability for Jump Start
AEC-Q100 Qualified

* Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device.
These are stress ratings only and functional operation of the device at these or any other conditions beyond those
indicated under “recommended operating conditions” is not implied.
Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
