Maxim Integrated MAX16923 automotive display power management IC

Designers of automotive electronic systems have the opportunity to increase the number of displays per vehicle while reducing design complexity by using the MAX16923 4-output display power IC with watchdog timer from Maxim Integrated Products. By replacing four or five discrete ICs with a single power management solution, the device shrinks solution size and should make 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, but designers are struggling with the complexity of adding these screens because the required power supply circuitry competes for space with a myriad of other electronic systems inside the car. By reducing the number of ICs needed to support each display, the MAX16923 is said to reduce design complexity and board size issues.

The product offers high integration with four power rails, featuring both a high-voltage and low-voltage buck converter, a high-voltage and low-voltage low-dropout (LDO) regulator, electromagnetic interference (EMI) mitigation and a watchdog timer in a single IC. Its high level of integration can reduce an automotive power solution from four or five ICs down to one chip, without making the temperature rise significantly. This is claimed to help ease design complexity and reduce the power solution size by up to 50% compared to competitor products. Spread spectrum, slew-rate controlled switching and programmable switching frequency reduce EMI interference on low noise signal to the display.
