MAX1823HEUB+T

Overview

The MAX1823HEUB+T is a dual USB power switch from Analog Devices Inc./Maxim Integrated, designed for portable applications. It features fault blanking and auto-reset capabilities to manage USB port connectivity. The device operates within a supply voltage range of 2.7V to 5.5V and draws a typical supply current of 50μA. It is housed in a compact 10-TFSOP, 10-MSOP package with dimensions of 0.118 inches (3.00mm) width. The component supports surface mount mounting and functions reliably across an operating temperature range of -40°C to 85°C.

Feature Summary

• Integrates dual USB power switches with fault blanking functionality to prevent nuisance tripping during hot-plug events.
• Includes auto-reset logic that automatically restores power after a fault condition clears, reducing system complexity.
• Provides overcurrent protection and undervoltage lockout to safeguard connected peripherals and the host system.

Applications

• USB hub designs requiring independent port control
• Portable peripheral devices needing power distribution management
• Space-constrained mobile electronics

Procurement Notes

Verify the specific ordering suffix (+T vs T) against the manufacturer's official documentation to ensure correct packaging configuration. Confirm that the 10-TFSOP/10-MSOP package variant matches your PCB footprint requirements. Cross-reference the lead time and availability directly with authorized distributors or Analog Devices, as these metrics fluctuate based on production schedules and regional stock levels.

Selection Notes

Select this component when designing systems requiring dual USB port isolation with automatic recovery from short-circuit conditions. The low quiescent current makes it suitable for battery-powered devices where standby power consumption is critical. Ensure the input voltage range aligns with the system's bus power specifications before integration into the circuit design.

Part Context

This part belongs to the Maxim Integrated USB Power Switch family, specifically engineered for managing USB connectivity in modern electronic devices. It addresses common issues such as port damage and system instability caused by faulty peripherals. The dual-channel architecture allows for independent control of two USB ports within a minimal footprint, supporting efficient board space utilization in dense layouts.
