MAX16813ATP+

LED Driver IC Overview

The MAX16813ATP+ is a four-channel high-brightness LED driver IC from Analog Devices/Maxim Integrated. It integrates four current-sink channels and an internal current-mode switching DC-DC controller supporting boost, coupled-inductor boost-buck, or SEPIC topologies. The device operates with an input voltage range of 4.75V to 40V and withstands direct automotive load-dump events. Each channel provides up to 150mA output current. The adjustable switching frequency ranges from 200kHz to 2MHz. It features PWM dimming, open LED protection, and shorted LED detection in a TQFN-20 package.

LED Driver IC Feature Summary

• Integrates four independent LED current-sink channels with programmable slope compensation for fast response.
• Includes an internal current-mode switching DC-DC controller to drive external converter stages.
• Provides comprehensive protection including output overvoltage, open-LED detection, and shorted LED protection.
• Supports wide input voltage range suitable for automotive applications with load-dump immunity.

LED Driver IC Applications

• Automotive LCD display backlighting
• General lighting systems
• High-brightness LED arrays

LED Driver IC Procurement Notes

Verify the specific suffix 'ATP+' against the official datasheet to confirm pinout and thermal characteristics. Confirm RoHS compliance status through manufacturer documentation. Check for obsolescence notices as Maxim products may transition to Analog Devices part numbers. Ensure the TQFN-20 package availability matches your manufacturing requirements.

LED Driver IC Selection Notes

Select this component when designing multi-string LED drivers requiring integrated power stage control. It is suitable for applications needing wide input voltage tolerance and automotive-grade reliability. Consider the four-channel architecture for uniform brightness control across multiple LED strings without external discrete current sources.

LED Driver IC Part Context

The MAX16813 belongs to the MAX168xx family of integrated LED drivers designed for high-efficiency lighting solutions. It combines power management and LED driving functions into a single IC, reducing component count and board space compared to discrete solutions. This integration simplifies design for complex lighting architectures.

LED Driver IC Replacement Considerations

The MAX16814ATP-V-T is a related four-channel variant with similar functionality but different packaging or operational nuances. Verify electrical compatibility and pin correspondence before substitution. Cross-reference with other MAX168xx series devices for potential upgrades or alternatives.
