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.
