Maxim's LED Matrix Manager Empowers High-Density Automotive Matrix and Pixel Lighting

SAN JOSE, Calif., Oct. 10, 2018 /PRNewswire/ -- Designers of high-performance automotive matrix lighting and adaptive driving beam light-emitting diode (LED) applications can now migrate to higher current devices while reducing solution size and improving flexibility with the MAX20092 12-switch matrix manager from Maxim Integrated Products, Inc. (NASDAQ: MXIM). The IC minimizes thermal issues associated with LED matrix lighting applications by offering the industry's lowest internal switch resistance (R(DS_ON)), which is 65 percent lower than the closest competitive solution.

Safety and brand differentiation are two of the leading factors driving greater adoption of LEDs in automotive front-lighting platforms, which are growing at 30 percent per year, according to Strategy Analytics, Inc. As part of their distinctive brand identities, OEMs are designing in advanced safety features such as glare-free high beams along with LED and matrix lighting. However, LED lighting designers are challenged with increasing power, thermal and design complexities.

The MAX20092 provides flexible current management for matrix and pixel lighting. Twelve integrated switches control LEDs in string voltages up to 56V, saving design time and reducing complexity. Its integrated MOSFET on resistance (R(DS_ON)) of 70 mohm is the lowest in the industry - comfortably driving LED currents up to 1.5A. Maxim's 12-switch LED matrix manager is offered in a small 5mm x 5mm TQFN package. Additionally, Maxim today introduced MAX20096 and MAX20097 dual-channel, synchronous buck high-brightness LED controllers to work with the MAX20092, helping designers improve transient response times in LED lighting. The MAX20096 and MAX20097 deliver ultra-fast transient response with near-fixed frequency with Maxim's proprietary average current mode control scheme, minimizing EMI and enabling a reliable, high-performing design.

Key Advantages of MAX20092

    --  Integration: Reduces bill of materials (BOM) costs while saving space.
        Manages one to two LEDs per switch with 12-bit pulse-width modulation
        (PWM) dimming. Provides built-in logarithmic fade-in/fade-out capability
        that simplifies LED programmability and reduces taxation on system bus
        lines.
    --  High Performance and Safety: Low R(DS_ON) of 70 mohm safely enables LED
        current of up to 1.5A. Features advanced fault protection and management
        for open, short and open-trace LED detection.
    --  Flexibility: Can parallel up to 27 MAX20092 devices without
        daisy-chaining to manage large LED pixel count of up to 324 LEDs; allows
        designers to configure 1 string x 12 series switches, 2 strings x 6
        series switches, and 4 strings x 3 series switches from each IC.
    --  Electromagnetic Interference (EMI) Mitigation: Slew-rate control reduces
        EMI and noise

Commentary

    --  "Although matrix LED headlights enhance safety, they were once
        exclusively for the premium auto sector, due to their complexity and
        high cost," said Kevin Mak, senior analyst for the Automotive Practice
        of Strategy Analytics. "Technology developments that enhance LED
        efficiency and performance will drive their greater adoption into
        automotive platforms. Maxim's MAX20092 is one of the solutions that
        aligns with greater adoption trends for LED lighting in automotive
        applications."
    --  "Maxim designed the MAX20092 to help developers who want to utilize more
        LEDs in their designs and reduce the BOM cost and solution space," said
        Yin Wu, business manager for the Automotive Business Unit at Maxim
        Integrated. "The safety and OEM branding value that LEDs present are
        compelling, and we enable their adoption in greater numbers through
        higher flexibility and reliability."

Availability and Pricing

    --  The MAX20092 is available at Maxim's website for $2.93 (1000-up, FOB
        USA)
    --  The MAX20092EVSYS# evaluation kit includes a graphical user interface,
        matrix manager board and an LED adapter board featuring Osram Opto
        Semiconductors' Oslon Compact PL, KW CELNM1.TG, LED components, which
        are suitable for adaptive matrix-style headlights
