Product Description


Automotive Direction Indicator IC




  • The bipolar integrated circuit U2043C is used in relay-controlled automotive flashers where a high-level EMC is required.
  • Lamp outage is indicated by frequency doubling during hazard warning as well as direction mode.



  • Quiescent current <5mA
  • Wide operating voltage, up to 33V
  • Strong anti-interference ability

Functional Description

  • The circuit is directly coupled by an external RC circuit that input triangular wave oscillation signal, through a controlled oscillator, current amplification, the output drive capability with a strong square wave pulse.
  • When the sampling resistor Rs monitoring to reduce the half of lamp load, the corresponding voltage comparator action, causing changes in the oscillation frequency doubles.
  • When the supply voltage produces a transient pulse (±100V), the protection circuit automatically turns on shunting and clamping limit, to interference protection purposes.
  • The relay drive current output of the circuit is 120-200mA.
