A6260  
High Brightness LED Current Regulator  
Features and Benefits  
Automotive grade  
LED drive current up to 350 mA  
6 to 40 V supply  
Reverse battery protection  
Low drop-out voltage  
LED short circuit and thermal protection  
10 μA maximum shutdown current  
PWM dimming control input  
Current slew rate limiting  
Description  
The A6260 is a linear, programmable current regulator  
providing up to 350 mA for driving high-brightness LEDs.  
The LED current, accurate to 4%, is set by a single low-power  
sense resistor. Driving LEDs with constant current ensures  
safe operation with maximum possible light output.  
For automotive applications, optimum performance is  
achieved when driving between 1 and 3 LEDs at cur-  
rents up to 350 mA.  
The low dropout voltage of the A6260 allows a single white  
LED to be driven safely, at full current, with a supply voltage  
down to 6 V.  
An enable input allows PWM dimming and can be used to  
enable low-current sleep mode. The rate of change of current  
during PWM switching is limited to reduce EMI.  
Package: 8-pin SOIC with exposed  
thermal pad (suffix LJ)  
Overcurrent detection is provided to protect the LEDs and  
the A6260 during short-to-supply or short-to-ground at any  
LED terminal.  
The integrated temperature monitor can be used to reduce  
the LED drive current if the chip temperature exceeds the  
thermal limit.
