Diodes Incorporated’s Automotive-Compliant Linear LED Driver-Controller Features Low Dropout and Enhanced Dimming
July 02 2019 - 10:00AM
Business Wire
Diodes Incorporated (Nasdaq: DIOD) today announced the AL5814Q,
an automotive-compliant linear LED driver-controller with low
dropout voltage and open LED detection for automotive linear-driven
LED lamps.
The AL5814Q is suitable for automotive applications requiring
specific change control and is AEC-Q100 qualified, has a grade 1
temperature rating, is PPAP capable, and is manufactured in
IATF16949:2016 certified facilities. The device operates from an
input voltage in the range of 4.5V to 60V. It has up to 15mA drive
and uses an external drive transistor, MOSFET or BJTs, minimizing
its power dissipation. This ability to drive higher current LEDs or
multiple LED strings makes it suitable for applications that
require higher light output including license plate illumination,
rear lamps, internal lamps, and instrument panels.
The AL5814Q’s VSET pin can be used to adjust output current
feedback level for a lower dropout via resistor divider, analog
dimming and thermal fold-back, the latter being implemented using
an NTC resistor.
PWM dimming is supported through applying a PWM signal to the
VFAULT pin. Over-temperature protection is also included, along
with input under-voltage lockout. Open-LED detection, via the
VFAULT pin, can also be supported with its activation via the
SFAULT pin.
The AL5814Q’s tight 0.4V reference voltage (±5% across
temperature) provides a high level of thermal stability and
matching between lamps.
The AL5814Q is available in the exposed MSOP-8EP package.
