MAX7302AEE+

LED Driver IC Overview

The MAX7302AEE+ is a 9-port I/O expander and LED driver manufactured by Analog Devices Inc. (Maxim Integrated). It integrates GPIO expansion with linear LED dimming capabilities in a single QSOP-16 package. The device operates on a supply voltage range of 1.62V to 3.6V, supporting low-power applications. It features an output current capability of 25mA per channel and supports communication frequencies up to 1MHz. The component is designed for surface-mount installation and functions within an operating temperature range of -40°C to +125°C.

LED Driver IC Feature Summary

• Integrates nine general-purpose input/output ports with dedicated linear LED driving functionality.
• Supports level translation between different logic voltage domains for flexible system interfacing.
• Provides precise linear dimming control for LED brightness adjustment without external components.

LED Driver IC Applications

• Portable electronic devices requiring combined I/O expansion and display backlighting.
• Industrial networking equipment utilizing Power over Ethernet (PoE) controllers.
• Embedded systems needing compact GPIO expansion with integrated status indication.

LED Driver IC Procurement Notes

Verify the specific suffix 'AEE+' against the official datasheet to confirm pinout and electrical characteristics match your design requirements. Confirm RoHS compliance status through the manufacturer's documentation. Check current availability as distribution channels may list this part as limited stock or obsolete. Ensure the QSOP-16 footprint matches your PCB layout constraints before finalizing procurement.

LED Driver IC Selection Notes

Select this component when a single IC must handle both digital I/O expansion and analog LED dimming tasks. It is suitable for designs constrained by board space where separate GPIO and LED driver chips are not feasible. Consider the 1.62V minimum supply voltage for battery-operated applications. Verify that the 25mA output current meets the load requirements for the connected LEDs or peripherals.
