Overview
UNISONIC TECHNOLOGIES CO.
, LTD U2043 LINEAR INTEGRATED CIRCUIT FLASHER, SHUNT, PILOT LAMP TO GND OR VBATT  DESCRIPTION The UTC U2043 is designed to use 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 VBatt or GND.
DIP-8  FEATURES *Temperature and voltage compensated frequency *Warning indication of lamp failure by means of frequency doubling * Minimum lamp load for flasher operation ≥10 W *Relay output with high current carrying capacity and low saturation voltage *Low susceptibility to EMI SOP-8  ORDERING INFORMATION Note: Order Number Lead Free Halogen Free U2043L-D08-T U2043G-D08-T U2043L-S08-R U2043G-S08-R Pin Assignment: G: Gate D: Drain S: Source Package DIP-8 SOP-8 U2043G-D08-T (1)Packing Type (1) T: Tube, R: Tape Reel (2)Package Type (2) D08: DIP-8, S08: SOP-8 Packing Tube Tape Reel (3)Green Package (3) G: Halogen Free and Lead Free, L: Lead Free  MARKING □ □ 87 6 5 UTC U2043 1 2 34 Date Code L: Lead Free G: Halogen Free Lot Code www.
