Maxim Integrated Korea released the 'MAX25605' sequential LED controller on the 5th. This allows sequential LED lighting, which was previously only applied to luxury vehicles due to its complex design and high cost, to be applied inexpensively to general and popular models.
The MAX25605 can be developed without a microcontroller or software. Its high integration speeds development and time-to-market and simplifies design. It also reduces design space by up to 50 percent and component count, reducing BOM costs by up to 25 percent compared to competing products.

Additionally, it can control LED currents up to 750 mA, offering greater flexibility in lighting design. It integrates six switches, each controlling three LEDs, and allows for serial connection of up to 16 devices without a microcontroller or software. Furthermore, this integrated solution allows designers to precisely program sequence timing, direction, and linear/logarithmic dimming, and easily detect fault conditions.

“Hardware programming simplifies development and provides flexibility in meeting lumen specifications by controlling LED current up to 750mA,” said Woo, Automotive Business Unit Manager.
