High-Voltage, Linear High-Brightness LED
Driver with Open-LED Fault Detect
General Description
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.
An on-board pass element minimizes external compo-
nent count while providing Q 5% 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.
Additional features include thermal and open-LED
protection 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-
