DESCRIPTION

· The U2044B is an integrated circuit designed for relay-controlled automotive flashers.
· It features two output stages for separate control of each vehicle side.
· Includes left, right, and hazard warning inputs with minimal control current.
· Direct battery connection is possible due to its extremely low current consumption.

FEATURES

· Temperature and supply voltage compensated flashing frequency.
· Frequency doubling indicates lamp outage.
· Two relay driver outputs with high current capacity and low saturation voltage.
· Minimum lamp load for operation: ≥ 1W.
· Low susceptibility to EMI and protection according to ISO/TR7637/1 Level 4.
· Reverse polarity protection and current consumption < 10 µA with switches open.

APPLICATIONS

· Automotive direction indicators and hazard warning systems.
· Suitable for vehicles requiring efficient and reliable flasher systems.
