Diodes Incorporated announced the availability of the AL5816Q automotive-compliant linear LED controller for automotive lighting. With an operating voltage range of 4.5V to 60V, the AL5816Q supplies an output drive current of 15mA to control LED lights through an external BJT, delivering a constant current up to 1.5A, or higher LED current if a MOSFET is used.
The 5-pin SOT25 package requires very few external components and does not need a separate switching inductor, with a high-voltage PWM input for dimming. The feedback pin operates at 200mV, enabling the AL5816Q to control the LED drive current while minimizing the drop-out voltage and reducing power dissipation.
The high-output drive current allows the AL5816Q to drive a single LED, an LED chain or multiple LED channels, as required, and the PWM dimming input accepts a signal operating at up to 50kHz. Protection features include input undervoltage lockout and overtemperature shutdown. From $0.18 each in 1,000-piece quantities.
