Robust and Flexible, Automotive Buck, LED Drivers from Diodes Incorporated Streamline Interior and Exterior Lighting
July 23 2019 - 10:00AM
Business Wire
Diodes Incorporated (Nasdaq: DIOD) introduced two automotive LED
drivers that combine robust performance, simplified design, and
flexibility to address internal and external lighting applications,
such as fog lamps, position lamps, rear lamps, and door lamps.
The AL8860Q and AL8861Q have a wide-operating voltage range from
4.5V to 40V to withstand load-dump events and operate correctly at
low-cranking voltages in stop-start applications. Leveraging
hysteretic-mode buck control simplifies the design of the feedback
loop, enabling inherent stability with only four external
components. Designers can save real estate and minimize the
electronic bill of materials due to the integrated, main power
MOSFET and a programmable switching frequency up to 1MHz that
allows a small output inductor.
The devices can source 1.5A for powering loads up to 40W
depending on supply voltage and external components. In addition,
both drivers support 0.3V to 2.5V analog dimming as well as
high-precision PWM dimming from 1% to 100% to allow various
automatic or user-adjustable brightness controls. Such flexibility
enables use in a wide variety of applications inside and outside
the vehicle, permitting designers to create multiple lamp types
efficiently using the same driver and streamline inventory
management for manufacturing.
Comprehensive built-in protection features ensure reliability
and safety, including short-circuit and open-LED protection as well
as overtemperature shutdown. The AL8861Q additionally features
current-sense resistor, short-circuit protection.
Both drivers are packaged in the high-power density MSOP-8EP
with support for analog and PWM dimming via one control pin. This
control pin, with its analog dimming function, can be used for
soft-start of the LED current with only one capacitor.
The AL8860Q and AL8861Q are automotive-compliant and support
PPAP documents. AL8860Q and AL8861Q are qualified to AEC-Q100 Grade
1.
