MAX1838EEE+

Overview

The MAX1838EEE+ is a dual high-side power switch IC designed for USB power distribution applications. It features an integrated 1.2 A output current capability per channel within a QSOP-16 surface-mount package. The device operates with an input voltage range of 2.25 V to 5.5 V and supports two independent outputs. Key electrical parameters include a specified operating temperature range from -40°C to +85°C. The component incorporates fault blanking and auto-reset functionality to manage transient conditions effectively.

Feature Summary

• Integrates dual high-side power switches with built-in fault protection mechanisms
• Features automatic reset logic to recover from overcurrent or short-circuit events without manual intervention
• Includes fault blanking circuitry to prevent nuisance tripping during startup transients

Applications

• USB port power distribution in embedded systems
• Hot-plug capable power switching circuits
• Overcurrent protection for peripheral devices

Procurement Notes

Verify the specific suffix and tape/reel versus tube packaging options available from authorized distributors, as supply status may vary by region. Confirm RoHS compliance documentation matches the current revision. Cross-reference the manufacturer part number with official Analog Devices databases to ensure authenticity and check for any recent lifecycle changes or obsolescence notices before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring independent control of two high-side loads with automatic recovery from fault conditions. Ensure the application input voltage remains within the 2.25 V to 5.5 V range. Consider the thermal performance of the QSOP-16 package relative to the expected load current and ambient temperature constraints to maintain reliable operation within the specified industrial temperature limits.

Part Context

The MAX1838EEE+ belongs to the Maxim Integrated line of specialized power management integrated circuits. It is categorized under power switch ICs and power distribution controllers. This series targets applications needing robust protection against electrical faults while maintaining system availability through automatic reset capabilities, distinguishing it from standard mechanical switches or non-resettable fuses.
