MAX16823ATE/V+

LED Driver IC Overview

The MAX16823ATE/V+ is a high-voltage, three-channel linear LED driver designed for high-brightness LED applications. It operates from an input voltage range of 5.5V to 40V and delivers up to 100mA per channel. The device features a boost topology with a maximum output voltage of 39.3V and a switching frequency of 3kHz. Packaged in a thermally enhanced 16-pin TQFN-EP (5mm x 5mm) housing, it supports PWM dimming and includes open LED protection. The component is AEC-Q100 qualified and specified for operation between -40°C and +125°C.

LED Driver IC Feature Summary

• Three independent channels with programmable constant current control via external sense resistors
• Integrated open-drain LEDGOOD output for real-time open LED detection
• Built-in 3.4V regulated output providing 4mA capability for auxiliary circuitry
• Wave-shaping circuitry designed to reduce electromagnetic interference

LED Driver IC Applications

• Automotive rear combination lamp LED drivers
• High-voltage automotive lighting systems requiring load-dump withstand
• Industrial high-brightness LED illumination arrays

LED Driver IC Procurement Notes

Verify the specific suffix V+ indicates lead-free compliance and RoHS status before ordering. Confirm package availability as distribution may vary by region. Ensure the design accounts for the 16-TQFN thermal pad requirements for adequate heat dissipation during continuous operation at maximum current loads.

LED Driver IC Selection Notes

Select this component when a linear solution is preferred for simplicity over switch-mode topologies. It is suitable for designs requiring precise ±5% current accuracy without complex feedback loops. Consider the low dropout voltage of pass elements for efficiency near the minimum input voltage threshold.

LED Driver IC Part Context

This part belongs to the MAX16823 family of high-voltage LED drivers. Variants such as MAX16823AUE/V+ offer alternative packaging like TSSOP-16, while MAX16823ATE/V+T provides tape-and-reel options. All variants share the core three-channel functionality and automotive-grade specifications.

LED Driver IC Replacement Considerations

Direct substitutes include MAX16823AUE/V+ for pin-compatible TSSOP replacement or MAX16823ATE/V+T for reel-based assembly. Verify that any substitute maintains the same AEC-Q100 qualification and thermal performance characteristics.

LED Driver IC FAQ

How does the device handle open LED conditions?

The MAX16823ATE/V+ includes an active-high, open-drain LEDGOOD output that signals when an open LED condition is detected on any of the three channels.

What is the maximum input voltage tolerance?

The device operates within a 5.5V to 40V input range and can withstand load-dump events up to 45V, making it suitable for automotive environments.
