MAX1823AEUB+

Overview

The MAX1823AEUB+ is a dual USB power switch IC designed for portable applications. It operates within a 4V to 5.5V supply range and delivers up to 720mA output current per channel with a maximum on-resistance of 120mΩ. The device features integrated ±1kV/42Ω surge protection and fault blanking to prevent false triggering during hot-plug events. It includes an autoreset function that latches the switch off upon fault detection, requiring a reset signal to restore operation. The component functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Dual-channel architecture with integrated surge protection
• Fault blanking mechanism prevents false triggering
• Autoreset functionality for fault recovery

Applications

• Portable consumer electronics
• USB peripheral power distribution
• Battery-powered devices

Procurement Notes

Verify the specific suffix 'EUB+' against the manufacturer's official datasheet to confirm package type and RoHS compliance status. Ensure the ordering code matches the exact pinout and electrical specifications required for the design. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and avoid counterfeit components.

Selection Notes

Select this component when dual independent USB ports require overcurrent protection and surge immunity. The low on-resistance minimizes power loss in battery-operated systems. Verify that the input voltage range aligns with the system's power source. Consider the thermal performance and package size constraints for compact portable designs.
