MAX7306AUB+

LED Driver IC Overview

The MAX7306AUB+ is a 4-port I/O expander and LED driver featuring integrated level translation, manufactured by Analog Devices Inc./Maxim Integrated. It operates on a supply voltage range of 1.62V to 3.6V with an output current capability of 25mA per channel. The device supports a 1MHz communication frequency and functions within an operating temperature range of -40°C to 125°C (TA). It is housed in a 10-uMAX-EP surface-mount package.

LED Driver IC Feature Summary

• Integrates general-purpose input/output expansion with dedicated LED driving capabilities
• Includes built-in level translation for interfacing between different voltage domains
• Supports high-speed I2C communication interface

LED Driver IC Applications

• Backlight control systems
• Portable electronic devices requiring GPIO expansion
• Embedded systems with mixed-voltage logic interfaces

LED Driver IC Procurement Notes

Verify the specific suffix 'AUB+' against the official datasheet to confirm the 10-uMAX-EP package and lead-free status. Ensure compatibility with the required supply voltage range and thermal specifications for the target application environment before finalizing procurement.

LED Driver IC Selection Notes

Select this component when both GPIO expansion and LED driving are required in a single package. The integrated level translation simplifies design by eliminating external translators. Verify that the 25mA output current meets the load requirements and that the 10-pin footprint fits the PCB layout constraints.

LED Driver IC Part Context

This part belongs to the MAX7306 series of interface ICs designed for space-constrained applications. It combines standard I/O expansion functions with LED driver features, offering a consolidated solution for managing multiple peripherals and indicators in compact electronic designs.

LED Driver IC Replacement Considerations

Check for direct pin-compatible substitutes within the MAX7306 family, such as variants with different packaging or temperature ratings. Ensure any replacement maintains the same level translation functionality and electrical characteristics.
