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
SOP-14
DIP- 14
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 switcwwhwe.DsataoSpheeet4nU).com
* Reverse polarity protection
* Three control inputs: left, right and hazard warning
*Pb-free plating product number: LL204L
