The U2044B from Atmel is an integrated circuit designed for use in relay-controlled automotive flashers. It features two output stages, allowing for separate control of each side of the vehicle. This dual output capability simplifies the construction of hazard warning systems.
Key features include temperature and supply voltage compensation for flashing frequency, frequency doubling to indicate lamp outages, and high current-carrying capacity relay driver outputs. The device boasts extremely low current consumption, less than 10 µA when switches are open, enabling direct connection to the battery. It also includes protection according to ISO/TR7637/1 Level 4 and reverse polarity protection.
The U2044B is housed in a SOIC package. It operates within a temperature range of -40°C to 100°C. The minimum lamp load for flasher operation is 1W. Its design facilitates small load switch contacts due to a small control current requirement for the left and right direction indicator inputs.
