MAX16805ATP+T

LED Driver IC Overview

The MAX16805ATP+T is a linear high-brightness LED driver manufactured by Analog Devices Inc. (Maxim Integrated). It provides a constant output current of 350mA per channel and supports both analog and PWM dimming methods. The device operates within an ambient temperature range of -40°C to +125°C and is housed in a 20-pin TQFN surface-mount package.

LED Driver IC Feature Summary

• Integrates linear regulation for precise high-brightness LED current control
• Supports flexible dimming via analog voltage or pulse-width modulation signals
• Designed for automotive-grade reliability with extended temperature operation

LED Driver IC Applications

• Automotive exterior lighting systems
• Interior vehicle illumination modules
• General-purpose high-brightness LED arrays

LED Driver IC Procurement Notes

Verify the specific suffix 'ATP+T' against official Analog Devices documentation to confirm pinout, thermal pad configuration, and RoHS compliance status. Ensure the selected variant matches the required operating temperature grade and packaging specifications for the target design.

LED Driver IC Selection Notes

Select this component when a single-channel linear solution is sufficient for driving LEDs at up to 350mA. Consider alternative topologies if input-output voltage differentials result in excessive power dissipation that exceeds the thermal capabilities of the TQFN-20 package.

LED Driver IC Part Context

This part belongs to the Maxim Integrated line of LED drivers, now under Analog Devices. It serves as a dedicated controller for managing current in high-power LED applications, offering a compact footprint compared to discrete resistor-based current limiting solutions.

LED Driver IC Replacement Considerations

Consult official cross-reference lists for direct replacements. Verify compatibility regarding pin assignments, thermal resistance, and control signal interfaces before substituting with other linear LED driver ICs.
