LBRERSFRHAREA SHANGHA FUDAN MICROELECTRONICS CO, LTD Automotive Flashers Controller VG2043 The integrated circuit VG2043 is used in relay-controlled automotive flashers where a high EMC level is required. A lamp outage is indicated by frequency doubling during hazard mode as well as direction mode. The pilot lamp can be connected either to V,,, oF GND. eat FEATURES @ Temperature and voltage compensated frequency @ Warning indication of lamp failure by means of frequency doubling @ Minimum lamp load for flasher operation > 10W @ Relay output with high current carrying capacity and low saturation voltage @ Dip8 or Sop8 Package Two type supply voltage for selection: 2043C is for 24V) ABSOLUTE MAXIMUM RATINGS :12V and 24V (20438 is for 12V, Reference point ground PIN1,voltage:12V/24V parameters Symbot Value Unit PINS2.6 Supply voltage Vs 30.0 Vv Surge forward current \,=.1ms PINS2.6 -_ Ls A \=2ms PINS2.6 Joe 10 A =2ms PINS.
