A6261

Protected LED Array Driver

Features and Benefits

Description

▪ Total LED drive current up to 400 mA

▪ Current shared equally up to 100 mA by up to 4 strings

▪ 6 to 50 V supply

TheA6261isalinear,programmablecurrentregulatorproviding

up to 100 mAfrom each of four outputs to drive arrays of high

brightnessLEDs.TheregulatedLEDcurrentfromeachoutput,

accurate to 5%, is set by a single reference resistor. 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.

▪ Low dropout voltage

▪ LED output short-to-ground and thermal protection

▪ Disable on open LED detection option

▪ Enable input for PWM control

▪ Current slew rate limit during PWM

▪ Current set by reference resistor

▪ Automotive K-temperature range (–40°C to 150°C)

Output control is provided by an enable input, giving direct

control for PWM applications. Outputs can be connected in

parallel or left unused as required.

Short detection is provided to protect the LEDs and theA6261

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.

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.
