In automotive applications, multi-output controllers are created to give high efficiency for a variety of load currents while providing both step-up and step-down conversion.
The Global automotive multiple output controller market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
One 12-24 VAC or VDC input is converted by the Altronix ACM4 into four separately controlled, fuse-protected outputs. It is possible to transform these power outputs into dry form “C” contacts. A normally open (NO) dry trigger input from an access control system, card reader, keypad, push button, PIR, etc., or an open collector sink is used to activate outputs. Maglocks, electric strikes, magnetic door holds, and other access control hardware devices will all receive power via ACM4.
Dual buck controller ISL78264 from Renease operates over a broad VIN range of 3.75V to 42V. It is made to accommodate switching frequencies with a wide duty cycle between 200 kHz and 2.2 MHz. In normal operation, the ISL78264 easily supports step-down applications needing large output currents and incorporates reliable MOSFET drivers. Additionally, to function during automotive cranking and load dump pulses, the ISL78264 supports dropout operation and low 25ns on-time.
A dual-channel USB Power Delivery (PD) IC has been introduced by independent Semiconductor, a pioneer in Autotech solutions, which lowers component count, streamlines designs, and increases dependability of in-cabin charging systems for portable devices. The iND87300 is the most complete USB-PD firmware programmable controller in the automobile sector. It combines power conversion and control while supporting any arrangement of USB Type A and Type C ports.
Melexis introduced a sophisticated OLED multiple controller for use in automotive. The MLX81130, a highly integrated, intelligent controller that enables the control of both LEDs and OLEDs from a single device, has been introduced. The 25 programmable constant-current sources on the MLX81130 in a QFN 55 package are intended to allow ASIL B system integration.
Single-master, multiple-slave arrangements are how it was intended to work. The Melexis Light Bus (MeLiBu) interface is supported by each MLX81130, which has a 25 LED/OLED driving capacity. Development of static and animated lighting systems is made simpler. It is particularly appropriate for small OLED panels or rear combination lights (RCL).
More advanced lighting applications are being developed. OLED technology is starting to be used by manufacturers. Due to its smaller size, this provides better efficiency, uniformity, and design options.
The MLX81130 is a pioneer in its ability to support both OLEDs and LEDs, working in tandem with its high-speed communication Interface MeLiBu to enable vehicle makers to more efficiently realise value-added external lighting features.
The use of LEDs and OLEDs often necessitates two different types of drivers, two controllers, and possibly two full subsystems that are difficult to combine, as automotive experts will appreciate.
This is solved by the MLX81130, which has independently programmable outputs that can power both LEDs and OLEDs.Each unit can accommodate the expanded threshold range required by OLEDs while driving up to 25 separate LEDs or 8 RGB LEDs.
The total number of LEDs or OLEDs that can be managed by one Master is practically limitless because the MLX81130 has been designed to accommodate multiple-slave arrangements. A 32-bit maths co-processor and 32 KB of Flash are used to support the integrated 16-bit MLX16 FX pipelined microcontroller, which controls each constant current output.
Additionally included are a 10-bit ADC and two watchdog timers with independent clocks. PWM is a method for controlling outputs.In order to meet the demands of the market, these output currents can be programmed in steps of 1 mA between 0 mA and 15 mA and then 2 mA steps up to 30 mA per output. It is possible to bridge several MLX81130 outputs for even more output current.
