MAX1823AEUB+T

Overview

The MAX1823AEUB+T is a dual USB power switch IC from Analog Devices Inc./Maxim Integrated, designed for power distribution in portable and embedded systems. It operates within an input voltage range of 4 V to 5.5 V and provides two independent output channels. Each channel supports a continuous output current of 720 mA with a maximum current limit of 900 mA. The device features a typical on-resistance of 120 mOhms and includes fault blanking capabilities with a maximum run time and idle time of 3 ms. It is housed in a 10-uMAX/uSOP surface-mount package and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Dual-channel architecture for independent USB port power management
• Integrated fault blanking to prevent false triggering during startup or transient events
• Low on-resistance design for efficient power delivery and minimal heat generation
• Compact 10-pin uMAX package suitable for space-constrained mobile applications

Applications

• USB hub power distribution circuits
• Portable electronic device battery management
• Embedded system peripheral power switching
• Mobile phone and tablet charging port protection

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm RoHS3 compliance status with the supplier. Ensure the 10-uMAX package dimensions match your PCB footprint requirements. Check for lead-free soldering compatibility if required by your manufacturing process. Validate that the 4V-5.5V input range aligns with your system's power supply rails.

Selection Notes

Select this component when dual isolated USB outputs are required with integrated overcurrent protection. Consider the 120 mOhm on-resistance for efficiency calculations against alternative switches. Evaluate the 3 ms fault blanking timing against your system's startup characteristics. Compare the 720 mA continuous current rating against peak load demands. Verify the 10-pin package availability against your assembly line capabilities.
