MAX1574EEE

LED Driver IC Overview

The MAX1574EEE is a white LED charge pump driver manufactured by Analog Devices Inc./Maxim Integrated. It utilizes an adaptive 1x/2x topology to drive up to three white LEDs with regulated constant current for uniform intensity. The device operates within a supply voltage range of 2.7V to 5.5V and delivers a maximum output current of 180mA. It features a 3MHz switching frequency and includes integrated short-circuit protection, thermal shutdown, and open-LED detection. The component is housed in a compact 16-pin SSOP package.

LED Driver IC Feature Summary

• Adaptive 1x/2x charge pump topology ensures stable operation across varying input voltages
• Integrated constant current regulation maintains uniform LED brightness
• Built-in fault protection mechanisms including thermal shutdown and short-circuit protection

LED Driver IC Applications

• Portable electronic devices requiring high-brightness white LED illumination
• Mobile phone keypad and display backlighting systems
• Handheld instrument indicator lighting

LED Driver IC Procurement Notes

Verify the specific suffix 'EEE' corresponds to the 16-pin SSOP package variant. Confirm RoHS compliance status through official manufacturer documentation. Ensure the ordering part number matches the exact pinout and electrical specifications required for the target design.

LED Driver IC Selection Notes

Select this component when designing circuits that require driving multiple white LEDs from a single-cell lithium-ion or similar power source. Consider the 180mA current limit and 3MHz frequency when evaluating thermal performance and EMI constraints relative to other Maxim LED drivers.

LED Driver IC Part Context

This part belongs to the MAX1574 family of LED drivers. It is distinct from the MAX4674 analog switch and MAX5172 DAC found in related search results. The MAX1574 series focuses on portable lighting applications, differentiating it from general-purpose signal switches or data converters.
