Overview
UNISONIC TECHNOLOGIES CO.
, LTD LL204 LINEAR INTEGRATED CIRCUIT DUAL OUTPUT FLASHER  DESCRIPTION The UTC LL204 is a dual output stages flasher designed as a relay driver for flashing light control in automotive applications.
Both sides direction indicator input with only a small control current makes switch contacts for small loads possible.
Each side of the vehicle is controlled separately.
The construction of the hazard switch could be simplified due to hazard warning input is separate.
The flasher will dramatically increase the flash frequency by a typical ratio of 2:1 if lamp fault is detected.
The UTC LL204 can be directly connected to the battery due to extreme low current consumption.
 FEATURES * Temperature and supply voltage compensated flashing frequency * Frequency doubling indicates lamp fault.
* Two relay driver outputs with high current-carrying capacity and low saturation voltage * Minimum lamp load for flasher operation: ≥ 1W * Very low sensitivity to EMI * Extremely low current consumption<10μA ( at switches open) * Reverse polarity protection * Three control inputs: left, right and hazard warning  ORDERING INFORMATION Ordering Number Lead Free Halogen Free LL204L-D14-R LL204G-D14-R LL204L-S14-R LL204G-S14-R Package DIP-14 SOP-14 DIP-14 SOP-14 Packing Tube Tape Reel  MARKING DIP-14 SOP-14 14 13 12 11 10 9 UTC LL204 8 1 2 34 5 6 7 Date Code L: Lead Free G: Halogen Free Lot Code www.
