MAX1694EUB-TG069

Overview

The MAX1694EUB-TG069 is a current-limited USB switch manufactured by Analog Devices Inc./Maxim Integrated. It features a low on-resistance of 60mΩ and includes built-in fault blanking to prevent false triggering during transient events. The device provides an accurate preset current limit ranging from 0.7A to 1.0A, ensuring robust protection for downstream components. Designed for surface-mount applications, it operates within a temperature range of -40°C to +85°C and is housed in a compact 10-TFSOP package.

Feature Summary

• Integrated current limiting with preset thresholds between 0.7A and 1.0A
• Built-in fault blanking mechanism to ignore short-duration transients
• Low on-resistance of 60mΩ for minimal voltage drop and power loss
• High-side output configuration suitable for USB port protection

Applications

• USB port overcurrent protection
• Hot-plug capable USB hub circuits
• Portable electronic device power management
• Peripheral interface current limiting

Procurement Notes

Verify the specific suffix TG069 against the manufacturer's official datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the component source is authorized to guarantee authenticity and traceability. Cross-reference the RoHS status and packaging details with the latest product release notes before finalizing procurement orders.

Selection Notes

Select this component when designing USB interfaces requiring integrated overcurrent protection without external sensing resistors. The fixed current limit simplifies bill of materials and reduces board space compared to discrete solutions. Consider the 60mΩ on-resistance impact on system efficiency and thermal performance under continuous load conditions.

Part Context

This part belongs to the MAX1693/MAX1694 family of current-limited switches designed specifically for USB applications. These devices integrate high-side switching capabilities with precise current limiting and fault detection logic. The family is optimized for protecting USB ports and connected peripherals from damage due to short circuits or excessive current draw.

Replacement Considerations

Consult the official datasheet for direct pin-to-pin compatible alternatives within the same product family. Verify that any substitute maintains the 60mΩ on-resistance and similar current limit specifications to ensure circuit compatibility.
