MAX1823EUB+T

Overview

The MAX1823EUB+T is a dual-channel USB power switch IC manufactured by Analog Devices Inc./Maxim Integrated, housed in a 10-uMAX surface-mount package. It operates within a supply voltage range of 4V to 5.5V and delivers up to 720mA output current per channel with a maximum on-resistance of 120mOhms. The device features an internal current limit of 900mA and includes auto-reset protection mechanisms. It supports full-duplex operation across a temperature range of -40°C to +85°C, ensuring reliable performance in portable electronic applications requiring robust power distribution.

Feature Summary

• Dual-channel architecture providing independent power switching for two separate loads
• Integrated auto-reset fault protection mechanism to recover from overcurrent events without manual intervention
• Low on-resistance design minimizing power loss and heat generation during conduction
• Compact 10-uMAX packaging suitable for space-constrained portable device designs

Applications

• USB peripheral power management in mobile devices
• Battery-powered equipment requiring protected power distribution
• Portable electronics with multiple high-current subsystems
• Industrial control systems needing reliable USB interface power
