Automotive-Compliant 60V Fast Dimming Linear LED Controller from Diodes Incorporated Targets Automotive LED Lighting Applications

Sponsored by Businesswire

Diodes Incorporated (Nasdaq: DIOD), a leading global manufacturer and
supplier of high-quality application specific standard products within
the broad discrete, logic, analog and mixed-signal semiconductor
markets, today announced the availability of the AL5816Q, an
automotive-compliant linear LED controller for Automotive LED 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 of a few mA up to 1.5A, or higher LED
current if a MOSFET is used. This ability to optimize the external
transistor makes the AL5816Q well-suited for many automotive LED
lighting applications, such as rear light clusters, interior
illumination, instrument panels, and license plate lighting.

The combination of a high-input voltage and high-output drive current,
coupled with a versatile high-voltage PWM dimming feature, means
automotive manufacturers can realize a significantly lower BOM for a
wide range of automotive applications using the AL5816Q. The 5-pin SOT25
package requires very few external components and does not need a
separate switching inductor. It features a high-voltage PWM input for
LED light dimming.

The feedback pin operates at just 200mV, enabling the AL5816Q to control
the LED drive current precisely while minimizing the drop-out voltage
and reducing the LED system power dissipation, particularly when
compared against traditional linear LED controllers.

The high-output drive current allows the AL5816Q to drive a single LED,
an LED chain or multiple LED channels, as required by automotive
manufacturers. The PWM dimming input accepts a signal operating at up to
50kHz. The device also features a number of protection features
including input undervoltage lock-out and overtemperature shutdown.
