Automotive Display Power Management IC

Maxim Integrated has introduced MAX16923 4-output display power IC with watchdog timer, aimed for automotive display applications. The new power IC helps the designers of automotive electronic systems in increasing the number of displays per vehicle while reducing the design complexity. The MAX 16923 allows us to replace four or five discrete ICs, thus reduces complexity and shrinks the solution size and makes it easier for the designers to increase the number of displays from two to five per vehicle, or even more. The number of displays per vehicle can be increased as per the needs of the OEM (Original Equipment Manufacturer) to increase the attractiveness of the car with advanced instrument clusters, infotainment, heads-up displays, center displays, rear-seat entertainment, and smart mirror applications.

The MAX16923 offers high integration with four power rails, featuring both high-voltage (5V or 3.3V) and low voltage (3.3V, 1.8V, 1.2V, or 1.1V) buck converter, a high-voltage (3.3V) and low-voltage (3.3V, 1.8V, 1.5V, or 1.0V) low-dropout (LDO) regulator, electromagnetic interference (EMI) mitigation and a watchdog timer in a single IC. Although the high level of integration reduces the number of IC, there will not be any rise in temperature, eventually, it will reduce the complexity and reduce the power solution size by 50% compared to the closest competitive solutions. Additionally, EMI mitigation and the watchdog timer improve the reliability of each display.

Key Advantages

  • Smallest Solution Size: Offers the industry’s first automotive power management IC to integrate five functions (HV buck converter and LDO, LV buck converter and LDO and watchdog timer) into a single IC to reduce complexity and solution size.
  • Lower Cost:  Reducing a five-chip solution to a single chip shrinks space by up to 50 percent, achieving smaller PCB size and lower bill-of-material (BOM) costs.
  • Low EMI:  Spread spectrum, slew-rate controlled switching and programmable switching frequency reduce EMI interference on low noise signal to the display.

The MAX16923 is available on Maxim’s Website for purchase, pricing is available on request. For more information about the MAX16923, visit the official website of Maxim Integrated Products, Inc.
