1. Description
The bipolar integrated circuit ATA2069 is designed for the use in relay-operated auto motive flasher modules and makes it possible to detect the outage of flasher bulbs on the vehicle itself and also on a trailer. Vehicles with a trailer hook are equipped with additional pilot lamps in the dashboard. ATA2069 is off (i.e., the relay is deactivated) as long as the flasher switch (at contact +49a) is open. As soon as this switch is closed, the IC starts reliably with the bright phase.
 

Features
• Lamp Outage Indication for Car and Trailer
• Temperature and Supply Voltage Compensated Flashing Frequency
• Relay Driver Output with High Current Carrying Capacity and Low Saturation Voltage
• Minimum Lamp Load for Flasher Operation > 10W
