Business Wire
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. Further information is available at
