Infineon BCR562: High-Current SOT-23 LED Driver for Automotive and Industrial Applications

In the demanding environments of automotive and industrial applications, reliable and efficient LED driving is paramount. The Infineon BCR562 stands out as a highly integrated linear LED driver IC engineered to meet these rigorous requirements. Housed in a compact SOT-23 package, this device is designed to deliver a constant output current of up to 150 mA, making it an ideal solution for driving high-brightness LEDs in space-constrained designs.

A key strength of the BCR562 is its exceptional ability to simplify circuit design and reduce component count. It operates as a linear current sink, requiring only a single external resistor to set the desired output current. This not only minimizes the PCB footprint but also enhances overall system reliability. The IC incorporates built-in protection features, including thermal shutdown and over-current protection, which are critical for maintaining performance and preventing damage in harsh operating conditions characterized by wide voltage fluctuations and extreme temperatures.

The device's low dropout voltage ensures efficient operation even as the input voltage supply approaches the LED forward voltage, preserving battery life in automotive systems and optimizing power consumption in industrial equipment. Furthermore, its excellent line and load regulation guarantees consistent LED brightness, avoiding flicker that can be caused by variations in the supply voltage.

The BCR562 is particularly suited for a vast array of applications, from automotive interior and exterior lighting, such as daytime running lights (DRLs) and status indicators, to industrial control panel indicators and signage. Its robustness and reliability make it a cornerstone for designers seeking a cost-effective, high-performance, and simple LED driving solution.
