MAX1694EUB

Overview

The MAX1694EUB is a high-side USB current-limited power switch manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2.7 V to 5.5 V and features a typical on-resistance (Rds On) of 60 mΩ. The device provides a fixed current limit of 700 mA, with an accurate preset limit ranging from 0.7 A to 1.0 A. It includes built-in fault blanking, over-temperature protection, short-circuit protection, and under-voltage lockout (UVLO). The component is housed in a 10-pin µMAX or uSOP package and supports surface mount installation.

Feature Summary

• Integrates fixed current limiting with built-in fault blanking for robust USB application performance
• Provides comprehensive fault protection including over-temperature, short circuit, and under-voltage lockout
• Features a low on-resistance switch with a status flag output for system monitoring

Applications

• USB port power distribution and protection
• High-side load switching in portable electronic devices
• Current-limited power management circuits

Procurement Notes

Verify the specific suffix (e.g., +T) for reel or cut-tape packaging requirements. Confirm RoHS compliance status through official manufacturer documentation. Ensure the operating temperature range (-40°C to +85°C) aligns with your environmental specifications. Cross-reference the exact part number with the latest datasheet to confirm pinout and electrical characteristics before finalizing procurement.

Selection Notes

Select this component when a compact, high-side switch with integrated current limiting is required for USB interfaces. The 60 mΩ on-resistance minimizes power loss, while the 700 mA limit protects downstream loads. Consider the 10-pin µMAX package for space-constrained designs. Verify that the non-inverting input logic and status flag functionality meet the control interface requirements of the host system.

Part Context

The MAX1694EUB belongs to the MAX1693/MAX1694 family of current-limited switches designed primarily for USB applications. These devices offer precise current limiting and fault protection in small surface-mount packages. The series is characterized by its ability to handle transient faults without latching off, thanks to built-in fault blanking, making it suitable for hot-plug scenarios.
