MAX25024ATG/VY+

LED Driver IC Overview

The MAX25024ATG/VY+ is an automotive-grade, I2C-controlled LED driver IC featuring four independent output channels. It utilizes a boost or SEPIC topology to regulate current for high-voltage LED strings. The device operates with an input voltage range of 2.5 V to 36 V and supports switching frequencies between 400 kHz and 2.2 MHz. Each channel delivers a maximum output current of 150 mA at voltages up to 52 V. It integrates PWM dimming capabilities and includes internal switches for efficient power management in compact surface-mount packages.

LED Driver IC Feature Summary

• I2C interface enables digital control of channel configuration and dimming levels
• Supports both boost and SEPIC topologies for flexible LED string driving
• Integrates high-frequency PWM dimming for precise brightness adjustment
• Automotive qualification ensures reliability in demanding vehicle environments

LED Driver IC Applications

• Automotive interior ambient lighting systems
• Dashboard and instrument cluster backlighting
• Door panel and console accent illumination
• High-voltage LED string drivers in display modules

LED Driver IC Procurement Notes

Verify the complete part number including suffixes such as TG and VY+ against official Analog Devices documentation to ensure correct package type and tape-and-reel specifications. Confirm automotive grade requirements and operating temperature ranges match your design constraints before ordering.

LED Driver IC Selection Notes

Select this component when designing multi-channel LED lighting systems requiring individual channel control via I2C. It is suitable for applications needing high input voltage tolerance and flexible topology options like boost or SEPIC. Ensure the design accommodates the specified switching frequency range and thermal requirements for the SWTQFN-EP-24 package.

LED Driver IC Part Context

This device belongs to the Maxim Integrated automotive LED driver family, designed specifically for complex lighting architectures in modern vehicles. It complements other single-channel or lower-channel-count drivers by offering integrated multi-channel control, reducing board space and component count for sophisticated interior lighting designs.

LED Driver IC Replacement Considerations

Check for direct pin-compatible alternatives within the MAX25xxx series from Analog Devices. Verify that any substitute maintains the same I2C addressability, output current limits, and automotive AEC-Q100 qualification status.
