PMIC Shrinks and Simplifies Automotive Display Designs

Maxim Integrated Products has announced the MAX16923
4-output display power IC with watchdog timer. By replacing four or five
discrete ICs with a single power management solution, the MAX16923
significantly shrinks solution size and makes it easier for automotive
designers to increase the number of displays from two to five per vehicle or
even more.

According to Maxim, the number of automotive displays per
vehicle continues to grow as OEMs seek to make cars more attractive with
advanced instrument clusters, infotainment, heads-up displays, center displays,
rear-seat entertainment and smart mirror applications. Designers struggle 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, says the company.

The MAX16923 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
also helps ease design complexity and reduces the power solution size up to 50%
compared to the closest competitive solution, says Maxim. Additionally, EMI
mitigation and the watchdog timer improve reliability of each display.

The MAX16923 is available at Maxim’s website. Pricing
available upon request. The MAX16923EVKIT# evaluation kit is available for $50.
