MAX4915BEUK+T

Current Regulation/Management Overview

The MAX4915BEUK+T is a single-channel current-limit switch from the MAX4915 family, designed for load switching applications. It operates within a 2.3V to 5.5V input voltage range and features an internal on-resistance of 0.2Ω. The device provides a guaranteed current limit of 200mA to protect host systems from faulty load conditions. It includes a 14ms blanking time upon turn-on to allow transient voltages to settle before fault detection begins. The component is housed in a SOT-23-5 surface-mount package and supports an operating temperature range from -40°C to +85°C.

Current Regulation/Management Feature Summary

• Internal current limiting prevents damage to host devices caused by short circuits or overcurrent conditions.
• Low 0.2Ω on-resistance minimizes power loss during normal operation.
• Guaranteed 14ms blanking time ensures stable operation during initial load connection transients.

Current Regulation/Management Applications

• SDIO card slot protection
• General-purpose load switching
• Peripheral port current limiting

Current Regulation/Management Procurement Notes

Verify the specific suffix 'EUK' corresponds to the SOT-23-5 package and 200mA current limit variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation. Check for obsolescence notices or lifecycle changes directly with Analog Devices, as availability may vary by region and distributor.

Current Regulation/Management Selection Notes

Select this component when a single high-side switch with integrated 200mA current limiting is required. Ensure the 2.3V to 5.5V supply range matches the system design. Consider the 0.2Ω on-resistance for voltage drop calculations. Verify that the SOT-23-5 footprint fits the PCB layout constraints compared to other package options in the family.

Current Regulation/Management Part Context

This part belongs to the MAX4914B/MAX4915A/B/MAX4917A/B family of current-limit switches. These devices share similar architectural features but differ in current limit ratings (100mA, 200mA, 300mA) and package types. The MAX4915 specifically denotes the 200mA limit variant within this series.

Current Regulation/Management Replacement Considerations

Direct substitutes include other variants within the MAX4914B/MAX4915A/B/MAX4917A/B family, such as MAX4914BELT+T or MAX4917AEUK+T, provided the current limit rating and package type are compatible with the application requirements.
