General Description

The integrated circuit U2044B is used in relay-controlled automotive flashers.

With two output stages, each side of the vehicle is controlled separately.

A left and a right direction indicator input with only a small control current makes switch contacts for small loads possible.

Key Features

  • Temperature and Supply Voltage Compensated Flashing Frequency.
  • Frequency Doubling Indicates Lamp Outage.
  • Two Relay Driver Outputs with High Current-carrying Capacity and Low Saturation.
  • Voltage Minimum Lamp Load for Flasher Operation: ³ 1 W Very Low Susceptibility to EMI Protection According to ISO/TR7637/1 Level 4 Extremly Low Current Consumption < 10 µA (with Switches Open) Reverse Polarity Protection Three.
