MAX16835ATE+

LED Driver IC Overview

The MAX16835ATE+ is a high-voltage, adjustable linear LED driver designed for high-brightness applications. It operates from an input voltage range of 6.5V to 40V and delivers up to 350mA of output current. The device features a ±3.5% output current accuracy and includes an integrated pass element with a typical low-dropout voltage of 0.55V. It supports PWM dimming via a high-voltage enable pin and provides a +5V regulated output with 4mA source capability. The component is housed in a thermally enhanced 16-pin TQFN package (5mm x 5mm) and is specified for automotive temperature ranges.

LED Driver IC Feature Summary

• Automotive courtesy lighting systems
• Automotive instrument cluster illumination

LED Driver IC Procurement Notes

Verify the specific suffix 'ATE+' corresponds to the required automotive grade and RoHS compliance status. Confirm the package type matches the 16-TQFN (5x5mm) specification with exposed pad. Ensure the operating temperature range meets the -40°C to +125°C requirement for your intended environment. Cross-reference the datasheet revision to confirm feature availability such as the 5V regulator output.

LED Driver IC Selection Notes

Select this component when a linear topology is preferred for simplicity and low noise in high-voltage LED strings. It is suitable for designs requiring precise current regulation without complex switching circuitry. Consider the thermal performance of the TQFN package relative to the power dissipation at the maximum load current. Verify that the input voltage remains within the 6.5V to 40V window to ensure proper regulation.

LED Driver IC Part Context

This part belongs to the MAX16835 family of high-voltage LED drivers manufactured by Maxim Integrated, now part of Analog Devices. The series is engineered for automotive and industrial lighting applications where reliability and compact size are critical. The ATE+ designation indicates the automotive temperature extended variant in the standard tube packaging format.

LED Driver IC Replacement Considerations

Check for direct pin-compatible substitutes within the same product family or newer revisions from the manufacturer. Verify that any alternative maintains the 350mA current rating and 40V input tolerance. Ensure the replacement package matches the 16-TQFN footprint and thermal characteristics.
