With 2.5V to 60V input range, it drives LED strings of any length up to 60V total forward voltage. The preset 100mA output current requires no external components - simply place in series with the LED string. Internal thermal shutdown protects against overtemperature. The AEC-Q100 qualified AL5809Q variant is available for automotive applications.","working_principle":"The AL5809 uses an internal NPN Darlington pass element with a precision bandgap reference and current-setting resistor to regulate a constant 100mA through the LED string. The device maintains constant current as long as the input voltage exceeds the LED string forward voltage plus the dropout voltage (~1.2V). Excess voltage is dropped across the internal pass element and dissipated as heat. Thermal shutdown activates at approximately 160C junction temperature to prevent damage.","pin_description":"
