MAX7302ATE+

LED Driver IC Overview

The MAX7302ATE+ is a nine-port general-purpose input/output (GPIO) and LED driver integrated circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates on a supply voltage range of 1.62 V to 3.6 V and supports I2C/SMBus serial interfaces with a maximum clock frequency of 1 MHz. The device features linear current drivers capable of delivering up to 25 mA per channel, housed in a 16-pin TQFN package with an exposed pad for thermal management.

LED Driver IC Feature Summary

• Integrates nine individually controllable output channels suitable for GPIO expansion and LED driving applications
• Supports standard I2C and SMBus communication protocols for efficient microcontroller interfacing
• Includes configurable interrupt outputs to signal state changes or fault conditions to the host system

LED Driver IC Applications

• Mobile phone keypad and display backlight control
• Portable consumer electronics input/output expansion
• Embedded systems requiring additional GPIO ports via serial interface

LED Driver IC Procurement Notes

Verify component authenticity through authorized distributors due to limited availability status. Confirm package integrity and pin alignment upon receipt. Ensure storage conditions comply with moisture sensitivity levels specified in the datasheet. Validate part markings against official manufacturer documentation to prevent counterfeit substitution.

LED Driver IC Selection Notes

Select this component when nine independent low-current outputs are required within a compact footprint. Consider the 3.6 V maximum supply limit for compatibility with single-cell lithium-ion powered systems. Evaluate the need for interrupt functionality if real-time status monitoring is critical to the application design.

LED Driver IC Part Context

This device belongs to the MAX73xx series of I/O expanders designed for space-constrained portable applications. It complements other Maxim Integrated interface solutions by providing combined GPIO and LED drive capabilities in a single small-outline package, reducing bill-of-materials complexity for mobile devices.

LED Driver IC Replacement Considerations

Consult official cross-reference lists for direct functional equivalents. Verify pinout compatibility and register mapping before substituting with alternative I/O expanders from different manufacturers.
