A6264  
Automotive Stop/Tail LED Array Driver  
Features and Benefits  
Total LED drive current up to 400 mA  
Description  
TheA6264isalinear,programmablecurrentregulatorproviding  
Current shared equally up to 100 mA by up to 4 strings  
6 to 50 V supply  
Low dropout voltage  
LED output short-to-ground and thermal protection  
Enable input for PWM control  
Current slew rate limit during PWM  
Current set by reference resistor  
up to 100 mAfrom each of four outputs to drive arrays of high  
brightness LEDs. The LED current can be switched between  
high current and low current for stop/tail applications. The  
two LED current levels from each output, accurate to 5%,  
are set by two reference resistors. Current matching in each  
string is better than 10% without the use of ballast resistors.  
Driving LEDs with constant current ensures safe operation  
with maximum possible light output.  
Automotive K-temperature range (–40°C to 150°C)  
Optimumperformanceisachievedwhendriving4stringswith  
1 to 3 LEDs in each string, at a total current of up to 100 mA  
in each string. Outputs can be connected in parallel or left  
unused as required.  
Applications:  
Automotive tail, stop, and turn lights  
Short detection is provided to protect the LEDs and theA6264  
during a short-to-ground at any LED output pin.An open LED  
in any of the strings disables all outputs but can be overridden.  
Shorted LED output pins or open LEDs are indicated by a  
fault flag.  
Packages  
10-pin MSOP with  
exposed thermal pad  
(suffix LY)  
A temperature monitor is included to reduce the LED drive  
current if the chip temperature exceeds a thermal threshold.  
16-pin TSSOP with  
exposed thermal pad  
(suffix LP)  
The device packages are a 10-pin MSOP (LY) and a 16-pin  
TSSOP (LP), both with exposed pad for enhanced thermal  
dissipation. They are lead (Pb) free, with 100% matte tin  
leadframe plating.
