MAX4791EUK/V+T

Current Regulation/Management Overview

The MAX4791EUK/V+T is a single-channel current-limiting power switch manufactured by Analog Devices Inc./Maxim Integrated. It operates within an input voltage range of 2.3V to 5.5V and provides a continuous output current of 250mA. The device is housed in a SOT-23-5 surface-mount package and is rated for an operating temperature range of -40°C to +85°C.

Current Regulation/Management Feature Summary

• Integrated current limiting functionality for circuit protection
• Low-side switching architecture for load control
• Compact SOT-23-5 surface-mount packaging

Current Regulation/Management Applications

• Portable electronic devices requiring overcurrent protection
• Battery-powered systems with low-voltage operation
• Peripheral interface circuits needing current-limited power distribution

Current Regulation/Management Procurement Notes

Verify the specific suffix (EUK vs V) against the manufacturer's official datasheet to confirm the exact current limit rating, as variations exist within this part family. Ensure the component meets RoHS compliance requirements for your target market. Confirm availability status directly with authorized distributors, as supply levels may fluctuate.

Current Regulation/Management Selection Notes

Select this component when a single-channel low-side switch with integrated 250mA current limiting is required. It is suitable for applications operating between 2.3V and 5.5V. Consider the SOT-23-5 package size for space-constrained designs. Verify thermal performance under maximum load conditions within the specified industrial temperature range.

Current Regulation/Management Part Context

This part belongs to the MAX479x series of current-limit switches from Maxim Integrated, now part of Analog Devices. The series includes variants with different current ratings such as 200mA and 300mA. These components are designed for protecting loads in portable and battery-operated equipment from short circuits and overcurrent conditions.

Current Regulation/Management Replacement Considerations

The MAX4791EUK+T is a compatible variant within the same series offering similar functionality. Verify pinout compatibility and current limit specifications before substitution. Other parts in the MAX479x family may serve as alternatives if current ratings differ.
