MAX16815ASA+T

LED Driver IC Overview

The MAX16815ASA+T is a high-voltage, linear LED driver IC designed for driving high-brightness LEDs. It features an adjustable linear current source capable of delivering up to 200mA with a single output channel. The device operates from a supply voltage range of 6.5V to 40V and supports PWM dimming for brightness control. Packaged in an 8-pin SO-EP (Exposed Pad) surface-mount package, it integrates short circuit and thermal protection mechanisms to ensure reliable operation in demanding lighting applications.

LED Driver IC Feature Summary

• Supports PWM dimming for precise brightness control
• Integrates short circuit and thermal protection
• Provides adjustable linear current regulation

LED Driver IC Applications

• High-brightness LED lighting systems
• General illumination drivers
• Automotive exterior lighting modules

LED Driver IC Procurement Notes

Verify the specific suffix designation (+T vs +) against the manufacturer's official datasheet to confirm packaging type and availability status. Confirm RoHS compliance details directly with Analog Devices or authorized distributors prior to procurement. Ensure the exposed pad thermal design matches the target PCB layout requirements for optimal heat dissipation.

LED Driver IC Selection Notes

Select this component when a simple, cost-effective linear solution is required for low-to-medium power LED strings. It is suitable for applications where input voltage exceeds LED forward voltage but does not justify the complexity of a switching regulator. Consider the thermal performance of the SO-EP package relative to the expected power dissipation in the final enclosure.

LED Driver IC Part Context

This part belongs to the MAX16815 series of high-voltage LED drivers from Maxim Integrated, now part of Analog Devices. The series focuses on providing robust, single-channel current regulation for high-brightness LEDs without the need for external inductors, simplifying the bill of materials compared to switching topologies.

LED Driver IC Replacement Considerations

The MAX16815ASA+ is a tube-packaged variant of the same functional device. Verify pinout compatibility and thermal characteristics before substituting between tape-and-reel and tube packages.
