MAX16813ATP/V+T

LED Driver IC Overview

The MAX16813ATP/V+T is an integrated, four-channel high-brightness LED driver IC designed for automotive and general lighting applications. It features a wide input voltage range of 4.75V to 40V and supports boost, coupled-inductor boost-buck, or SEPIC topologies with an adjustable switching frequency between 200kHz and 2MHz. Each channel provides up to 150mA output current. The device includes PWM dimming capabilities, open LED protection, and AEC-Q100 qualification for automotive reliability.

LED Driver IC Feature Summary

• Integrates four independent LED current-sink channels with a built-in current-mode DC-DC controller
• Supports flexible power converter topologies including boost, SEPIC, and coupled-inductor configurations
• Provides precise PWM dimming control and automatic open LED fault protection

LED Driver IC Applications

• Automotive head-up displays
• Small to medium-sized LCD backlighting in vehicles
• General high-brightness LED lighting systems

LED Driver IC Procurement Notes

Verify the specific suffix (V+) against the manufacturer's official datasheet to confirm package type and temperature grade. Confirm availability status as supply may be limited or restricted. Ensure the ordering part number matches the required tape-and-reel or cut-tape format specified in the procurement documentation.

LED Driver IC Selection Notes

Select this component when designing circuits requiring multiple high-brightness LED strings driven from a single wide-voltage source. The integrated DC-DC controller simplifies design by eliminating external switching components. Consider the TQFN-20 package for thermal performance and space-constrained layouts.

LED Driver IC Part Context

This part belongs to the MAX16813 series of integrated LED drivers manufactured by Analog Devices under the Maxim Integrated brand. It is specifically engineered for high-efficiency power management in automotive environments, offering robust protection features and compliance with automotive quality standards.

LED Driver IC Replacement Considerations

The MAX16814ATP-V-T is a related variant within the same family that also offers four channels but includes a dedicated high-voltage DC-DC controller section. Verify pin compatibility and internal topology differences before substitution.
