MAX16839ASA+

The MAX16839ASA+ is a high voltage, linear high brightness LED driver with open-LED fault detect in 8 pin NSOIC package. This programmable current regulator operates from 5V to 40V input voltage range and has an open-drain, constant current sink output capable of sinking up to 100mA. The MAX16839 is well suited for applications that require general purpose linear LED driver. The device directly withstands automotive load dump events of up to 45V. An on-board pass element minimizes external component count. It includes dimming input that controls duty cycle of output current allowing wide LED dimming range. The MAX16839 also includes thermal, open-LED protection and 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 flashing during subsequent power-up cycles.
