Simplify the Driving of Low-Power Lighting with Automotive LED Drivers from Diodes Incorporated


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 extends its family of automotive LED drivers with the
BCR4xxUQ series that simplifies the driving of low-power lighting. LED
technology is displacing conventional bulbs throughout the car: from
external lighting such as side markers, puddle lighting and sill plates,
to internal lighting including dome, ambient lights, instrument clusters
and button backlighting. The BCR4xxUQ series is designed to meet the
needs of all these applications, providing a simple, low-profile and
flexible approach to driving low-power LED strings.

Each of the devices in the BCR4xxUQ series can provide a pre-set current
output without the need for any external components, or deliver an
adjustable constant current between 10mA and 100mA (BCR401UQ, BCR402UQ,
BCR405UQ), 200mA (BCR420UQ), or 350mA (BCR421UQ) with ±10% tolerance.
All devices in the series are available in both industry-standard SOT26
and low-profile DFN2020 package options. The thinner 0.6mm DFN2020 is
designed for edge-lighting applications in which a less-intrusive,
lower-height package is required. All devices include negative
temperature coefficient, which lowers the LED driver current as the
internal temperature rises, thereby protecting and extending the
lifetime of the LEDs. In addition, the linear topology used means the
devices exhibit virtually no EMI.

With a wide operating voltage range of between 1.4V and 40V and total
power dissipation of up to 1.7W, the devices can be used to drive larger
strings of LEDs while still providing sufficient protection from
transients in a 12V automotive supply system. The BCR421UQ has the
advantage that it can be PWM dimmed directly from 3.3V MCU signal with
up to 25kHz and a duty cycle of 1%.
