MAX4915BELT+T

Current Regulation/Management Overview

The MAX4915BELT+T is a single-channel current-limit switch from the Maxim Integrated family, designed for power distribution applications. It operates within a 2.3V to 5.5V input voltage range and features a low 0.2Ω on-resistance. The device provides a guaranteed current limit of 200mA to protect host systems from faulty load conditions. It is housed in a compact 6-pin VSON package (SOLCC6) 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 during overcurrent events
• Low on-resistance minimizes power loss and voltage drop during conduction
• Guaranteed blanking time ensures stable operation when loads are connected
• Low shutdown reverse current reduces power consumption in disabled states

Current Regulation/Management Applications

• SDIO port protection and switching
• General-purpose load switching in embedded systems
• Power distribution in portable electronic devices

Current Regulation/Management Procurement Notes

Verify component authenticity through authorized Analog Devices distributors. Confirm RoHS compliance status and lead-free specifications against the official datasheet. Ensure storage and handling procedures meet moisture sensitivity level requirements for the VSON package to maintain reliability.

Current Regulation/Management Selection Notes

Select this part for applications requiring precise 200mA current limiting with minimal voltage drop. Consider the 2.3V to 5.5V supply range compatibility with system rails. Evaluate the VSON-6 footprint constraints against PCB layout requirements compared to alternative packages like SOT-23-5 or SOIC-5.

Current Regulation/Management Part Context

This component belongs to the MAX491x family of current-limit switches, which includes variants with 100mA, 200mA, and 300mA limits. The BEL suffix indicates a specific current limit rating and package type within this series, sharing functional characteristics with other members like the MAX4914B and MAX4917A/B.

Current Regulation/Management Replacement Considerations

Compatible substitutes include MAX4914BELT+T (100mA limit) and MAX4917BELT+T (300mA limit) from the same family. These parts share identical pinouts and packaging but differ in current threshold ratings. Verify that the alternative current limit meets the specific load protection requirements of the design.
