MAX16839 Linear High-Brightnes
max16839 linear high-brightness led driver with open-led fault detect
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 sinking up to 100ma. the max16839 is well suited for automotive 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 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 brightness in led strings.
additional features include thermal 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 detection also features fault memory, to avoid led flashing during subsequent power-up cycles.
the max16839 is available in thermally enhanced, 6-pin tdfn-ep and 8-pin so-ep packages and is specified over the -40°c to +125°c automotive temperature range.
