MAX4794ETT

Current Regulation/Management Overview

The MAX4794ETT is a high-side current-limiting regulator IC manufactured by Analog Devices Inc./Maxim Integrated. It provides overcurrent protection and limits output current to 375mA regardless of load conditions, which helps suppress inrush current but may cause voltage droop if the load exceeds this limit. The device operates within a supply voltage range of 2V to 5.5V and features a typical on-resistance of 1.8 ohms. It includes thermal shutdown protection and is housed in an SOT-23-5 package.

Current Regulation/Management Feature Summary

• High-side current limiting with fixed 375mA threshold
• Integrated thermal shutdown for overload protection
• Low on-resistance for minimal power loss
• Compact SOT-23-5 surface-mount packaging

Current Regulation/Management Applications

• Inrush current suppression in power distribution lines
• Overcurrent protection for sensitive downstream components
• Battery-powered device power management
• USB peripheral power switching

Current Regulation/Management Procurement Notes

Verify the exact part number suffix against official Analog Devices documentation to confirm pinout and electrical specifications. Ensure the component source is authorized to guarantee authenticity and compliance with RoHS standards. Cross-reference the datasheet revision date to ensure compatibility with your design requirements.

Current Regulation/Management Selection Notes

Select this component when a fixed 375mA current limit is required for high-side protection. Consider the voltage drop across the internal resistance under full load to ensure adequate headroom for downstream circuits. Evaluate thermal performance in enclosed environments due to power dissipation during current limiting events.

Current Regulation/Management Part Context

This part belongs to the Maxim Integrated line of power management solutions, specifically designed for compact, cost-effective current limiting applications. It complements other switches in the portfolio that offer adjustable or higher current thresholds, providing a standardized solution for protecting low-power loads.
