Do you know the latest automotive display power management IC?

What is the latest automotive display power management IC? What does it do? Maxim Integrated Products, Inc (NASDAQ: MXIM) announced the launch of the MAX16923 4-output display power supply IC with watchdog timer to help automotive system designers add automotive The number of displays used reduces design complexity. Using the MAX16923 monolithic power management solution instead of 4 to 5 discrete ICs can significantly reduce the size of the solution, allowing the automotive industry to easily increase the number of displays in each vehicle from 2 to 5 or more.

Nowadays, automotive OEMs are attracting consumers with new features such as advanced instrument clusters, infotainment systems, heads-up displays, central displays, rear-seat entertainment systems and smart rearview mirrors, thus increasing the number of displays inside the car. Increase. The power supply circuits required to add these displays will compete with the numerous electronic units in the car for space. The resulting complexity poses a huge challenge to designers.

The MAX16923 integrates four power rails and integrates high-voltage and low-voltage buck converters, high-voltage and low-voltage LDO regulators, electromagnetic interference (EMI) suppression, and a watchdog timer into a single IC. Its highly integrated design reduces the number of ICs in automotive power solutions from 4 to 5 to 1 without causing significant temperature rise. Compared with the closest competing solutions, this IC effectively reduces design complexity and reduces the size of the power supply solution by 50%. In addition, EMI suppression and watchdog timers help improve the reliability of each display.

Main advantages

·Smallest solution size: The industry’s first automotive power management IC that integrates five major functions into a single chip (high-voltage buck converter and LDO, low-voltage buck converter and LDO, watchdog timer), effectively reducing design complexity and reducing solution size size.

·Lower costs: Reduce the number of chips used in the system solution from 5 to 1, reducing the size by 50%, achieving the smallest PCB size and lower bill of materials (BOM) cost.

·Low EMI: Spread spectrum, slew-rate controlled switching operation and programmable switching frequency reduce EMI interference to low-noise signals input to the display.

"As OEMs continue to increase the number and size of displays inside vehicles, the automotive display field will achieve very strong growth in the next five years." Greg Basich, associate director of research for automotive infotainment and telematics services at Strategy Analytics, said: “Some high-end cars may use as many as 10 displays. Under this trend, designers need to integrate more and more electronic components into car systems. The huge challenges they face are limited space in the car and continuous functions. Extended conflict.

"By reducing the number of ICs required per display, the MAX16923 greatly reduces design complexity and board size." said Szukang Hsien, executive business manager, Automotive Division, Maxim Integrated: "This highly integrated solution works with the MAX20069 TFT The bias power supply and LED driver can meet all the power supply needs of 12.3-inch and smaller displays." The above is the analysis of the latest automotive display power management IC, I hope it can help you.
