MAX1823HEUB

Overview

The MAX1823HEUB is a dual USB switch integrated circuit designed for peripheral power management. It features two independent N-channel power switches with adjustable current limiting, overload protection, and over-temperature protection. The device operates within a supply voltage range of 4V to 5.5V and draws a typical supply current of 50µA. It supports an operating temperature range from -40°C to +85°C and is housed in a surface-mount 10-uMAX package.

Feature Summary

• Dual independent N-channel power switches
• Adjustable current limiting and fault blanking
• Integrated auto-reset functionality

Applications

• USB peripheral power management
• Portable electronic devices
• Battery charging systems

Procurement Notes

Verify the specific suffix (e.g., +T) for tape-and-reel packaging requirements. Confirm end-of-life status with the manufacturer or authorized distributors, as this component may be obsolete. Ensure the 10-uMAX package footprint matches your PCB design constraints before procurement.

Selection Notes

Select this component when dual-channel USB switching with built-in protection is required. Consider the 4V-5.5V input range and low quiescent current for battery-powered applications. Verify that the thermal performance in the 10-uMAX package meets the system's heat dissipation needs under maximum load conditions.

Part Context

This part belongs to Maxim Integrated's USB peripheral PMIC family. It integrates power switching and protection functions into a compact form factor. The device simplifies board space by combining dual switches with advanced fault handling capabilities, targeting mobile and embedded USB host or device applications.

Replacement Considerations

Check for direct cross-reference parts such as MAX1823AEUB+T. Verify pinout compatibility and electrical parameter alignment before substitution. Consult Analog Devices documentation for updated lifecycle status and recommended alternatives if this specific variant is discontinued.
