High-Voltage, Linear High-Brightness LED

Driver with Open-LED Fault Detect

General Description

Features

The MAX16839 programmable current regulator operates

from a 5V to 40V input voltage range and features an

open-drain, constant-current sink output capable of sink-

ing up to 100mA. The MAX16839 is well suited for auto-

motive applications and other applications that require a

general-purpose linear LED driver. The device directly

withstands automotive load dump events of up to 45V.

S Integrated 2I Open-Drain Pass Transistor

S 15mA to 100mA Programmable LED Current

S PWM Dimming

S Open-LED Fault Detection

S Open-LED Fault Event Status Memory

An onboard pass element minimizes external component

count while providing Q5% output current accuracy. The

MAX16839 includes a dimming input that controls the

duty cycle of the output current, allowing a wide LED

dimming range. In addition, the dimming input functions

as an on/off control of the output current. In multiple LED

string applications, the dimming input synchronizes the

LED current-sink turn-on, ensuring simultaneous bright-

ness in LED strings.

S -40NC to +125NC Operating Temperature Range

S Thermal Protection

S Undervoltage Lockout

Additional features include thermal and open-LED pro-

tection and an open-LED fault-detection output. In

multiple LED string applications where all FLTS pins are

connected together, an open-LED detection in one LED

string turns off all the strings simultaneously. Open-LED

protection also features fault memory, to avoid LED flash-

ing during subsequent power-up cycles.
