MAX4914AEUK+T

Current Regulation/Management Overview

The MAX4914AEUK+T is a single-channel current-limit power switch manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 2.3V to 5.5V and features an on-resistance of 0.2Ω. The device provides a guaranteed current limit of 100mA, with internal circuitry designed to prevent damage from faulty load conditions. It includes a 14ms blanking time to ensure transient voltages settle before current limiting activates. The component is housed in a SOT-23-5 package and supports operation across a temperature range of -40°C to +85°C.

Current Regulation/Management Feature Summary

• Integrates internal current limiting to protect host devices against short circuits or overloads.
• Features low on-resistance for efficient power distribution with minimal voltage drop.
• Includes a fixed blanking time to ignore initial load transients during turn-on.

Current Regulation/Management Applications

• SDIO card slot protection
• General-purpose load switching
• Portable electronic device power management

Current Regulation/Management Procurement Notes

Verify the specific suffix 'EUK' corresponds to the SOT-23-5 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation. Ensure the selected part number matches the required 100mA current limit specification for your design.

Current Regulation/Management Selection Notes

Select this component for applications requiring precise 100mA current limiting in compact designs. Consider the SOT-23-5 footprint constraints and the 2.3V minimum operating voltage. Evaluate if the fixed blanking time aligns with your load startup characteristics.

Current Regulation/Management Part Context

This part belongs to the MAX4914/MAX4915/MAX4917 family of current-limit switches. These devices share similar architectures but differ in current limit ratings (100mA, 200mA, 300mA) and package options. The MAX4914 specifically denotes the 100mA variant within this series.

Current Regulation/Management Replacement Considerations

Compatible substitutes include MAX4915A (200mA) and MAX4917A (300mA) from the same family, provided higher current capacity is acceptable. Verify pin compatibility and thermal performance when substituting.
