TION KIT EVALUA BLE AVAILA
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 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.
