By replacing four or five discrete integrated circuits with a single power management solution, the MAX16923 significantly reduces the size of the solution and makes it easier for automotive designers to increase the number of displays from two to five per vehicle, or even more.
The number of automotive displays per vehicle continues to grow as original equipment manufacturers (OEMs) seek to make vehicles more appealing with advanced instrument panels, infotainment systems, head-up displays, center displays, rear-seat entertainment, and smart mirror applications. Designers struggle with the complexity of incorporating these displays because the required power circuitry competes for space with other electronic systems within the car.
The MAX16923 offers high integration with four power lines, featuring a high- and low-voltage buck converter, a low-dropout (LDO) high- and low-voltage regulator, electromagnetic interference (EMI) mitigation, and a watchdog timer on a single IC. Its high level of integration can reduce an automotive power solution from four or five ICs to a single chip without a significant temperature increase. This also simplifies design complexity and reduces the size of the power solution by up to 50 percent compared to the closest competitive solution. Furthermore, the EMI mitigation and watchdog timer enhance the reliability of each display.
Key Advantages
- Smaller Solution Size: Offers the industry's first automotive power management IC that integrates five functions (AT-LDO buck converter, LV-LDO buck converter, and watchdog timer) into a single IC to reduce solution complexity and size.
- Lower Cost: Reducing the footprint from a five-chip solution to a single chip reduces space by up to 50 percent, resulting in a smaller PCB size and lower bill of materials (BOM) costs.
- Low EMI: Wide spectrum, controlled slew rate switching, and programmable switching frequency reduce EMI interference in the low-noise signal to the display.
