MAX16814CATP+

LED Driver IC Overview

The MAX16814CATP+ is a high-efficiency, integrated LED driver IC designed for high-brightness LED applications. It features four independent current-sink channels capable of delivering up to 150 mA per channel. The device incorporates an internal current-mode switching DC-DC controller supporting Boost, Buck, and SEPIC topologies with an adjustable operating frequency range from 200 kHz to 2 MHz. It accepts a wide input voltage range of 4.75 V to 40 V and withstands direct automotive load-dump events. The component operates within a temperature range of 0°C to +85°C and is housed in a TQFN-20 package.

LED Driver IC Feature Summary

• Integrates four independent LED current-sink channels with programmable slope compensation for fast response and simplified loop stability.
• Includes an internal current-mode switching DC-DC controller that supports multiple converter topologies including boost, coupled-inductor boost-buck, and SEPIC.
• Provides open LED protection and PWM dimming capabilities to ensure system safety and precise brightness control.

LED Driver IC Applications

• Small to medium-sized LCD displays in automotive environments
• General lighting applications requiring high-brightness LED driving
• Automotive systems needing direct load-dump event tolerance

LED Driver IC Procurement Notes

Verify the specific suffix CATP+ corresponds to the commercial temperature grade (0°C to +85°C) and TQFN-20 package configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the required Boost, Buck, or SEPIC topology given the integrated DC-DC controller specifications.

LED Driver IC Selection Notes

Select this component when designing circuits requiring four independent LED channels driven by a single integrated controller. It is suitable for applications demanding a wide input voltage range up to 40 V and robustness against automotive load-dump conditions. Consider the TQFN-20 package constraints and the need for external inductors and MOSFETs depending on the chosen converter topology.

LED Driver IC Part Context

This part belongs to the MAX16814C series of integrated LED drivers manufactured by Analog Devices / Maxim Integrated. It is distinct from other variants such as the MAX16814AUP/V+, which offers an extended industrial temperature range (-40°C to +125°C) and AEC-Q100 qualification. The CATP+ designation specifically denotes the commercial grade version packaged in a TQFN-20 footprint.

LED Driver IC Replacement Considerations

The MAX16814AUP/V+ serves as a qualified alternative for applications requiring extended temperature ranges and automotive certification. Verify pinout compatibility between the TQFN-20 and TSSOP-20 packages if substituting physical form factors. Ensure thermal management requirements align with the specific grade's operational limits.
