MAX16823ATE/V+T

LED Driver IC Overview

The MAX16823ATE/V+T is a high-voltage, three-channel linear LED driver designed for automotive applications. It operates from an input voltage range of 5.5V to 40V and delivers up to 100mA per channel. The device features ±5% output current accuracy, open LED detection, and three independent DIM inputs for PWM dimming. It includes a 3.4V regulated output with 4mA capability and withstands load-dump events up to 45V. Packaged in a thermally enhanced 16-pin TQFN-EP (5mm x 5mm), it is specified over the -40°C to +125°C temperature range.

LED Driver IC Feature Summary

• Three independent channels with adjustable constant output current and low dropout voltage pass elements
• Integrated open LED detection via active-high, open-drain LEDGOOD output
• Supports wide-range independent pulsed dimming through three dedicated DIM inputs
• Includes undervoltage lockout, short-circuit protection, and thermal shutdown

LED Driver IC Applications

• Automotive rear combination lamp LED drivers
• High-brightness LED lighting systems requiring high-voltage input
• Applications demanding precise LED current regulation and EMI reduction

LED Driver IC Procurement Notes

Verify component authenticity through authorized Analog Devices or Maxim Integrated distributors. Confirm package marking matches the 16-TQFN specification. Ensure the part meets AEC-Q100 automotive grade requirements for your specific application environment. Check for recent supply status updates as availability may vary by region.

LED Driver IC Selection Notes

Select this driver when a high-voltage linear solution is preferred for simplicity and cost. It is suitable for designs requiring up to 100mA per channel without external switching components. Consider the 5mm x 5mm TQFN package for space-constrained PCB layouts. Ensure the input voltage does not exceed 40V during normal operation.

LED Driver IC Part Context

This component belongs to the MAX16823 family of high-voltage LED drivers. It is manufactured by Analog Devices Inc., formerly Maxim Integrated. The device is part of a series designed for robust automotive lighting applications, offering integrated protections and precise current control in a compact surface-mount package.

LED Driver IC Replacement Considerations

Check for direct pin-to-pin replacements within the MAX16823 family variants. Verify that any substitute maintains the 3-channel configuration and 100mA per channel rating. Ensure the alternative supports the same 5.5V to 40V input range and automotive temperature specifications.
