Diodes Incorporated AEC-Q100 Qualified Linear LED Controllers

Diodes Inc. AEC-Q100 Qualified Linear LED Controllers are designed to meet the stringent requirements of automotive applications. These Linear LED Controllers monolithically integrate transistors, diodes, and resistors to function as a Constant Current Regulator (CCR) for linear LED driving.

LED technology displaces conventional bulbs throughout the automotive industry, from external lighting, such as side markers, puddle lighting, and sill plates, to internal lighting, including dome, ambient lights, instrument clusters, and button backlighting. These AEC-Q100 Qualified Linear LED Controllers are designed to meet the needs of all these applications, providing a simple, low-profile, and flexible approach to driving low-power LED strings.

Each LED Controller can provide a pre-set current output without external components or deliver an adjustable constant current controlled by a sense resistor connected across the FB pin and GND. Most of these devices can also be dimmed by a PWM signal through the PWM pin.

Diodes Inc. AEC-Q100 Qualified Linear LED Controllers are available in industry-standard SOT-25, SOT-26, low-profile DFN2020, and the thermally robust PowerDI®123 package options. These devices are all supported by PPAP (Production Part Approval Process) documentation, thus meeting all the requirements of the automotive electronics industry.
