MAX4995BAVB+

Current Regulation/Management Overview

The MAX4995BAVB+ is a high-side power distribution switch manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.7 V to 5.5 V and features a programmable current limit adjustable from 50 mA to 600 mA. The device utilizes a 10-UTQFN package with dimensions of 1.4 mm x 1.8 mm, suitable for surface-mount installation. It supports an operating temperature range from -40°C to +125°C and includes internal protection mechanisms such as thermal shutdown and reverse-current blocking.

Current Regulation/Management Feature Summary

• Programmable current limiting allows precise control of output load current via an external resistor.
• Integrated thermal shutdown protects the device from overheating under fault conditions.
• Reverse-current blocking prevents backflow when the input voltage drops below the output voltage.

Current Regulation/Management Applications

• USB port power switching and overcurrent protection
• Peripheral power distribution in embedded systems
• Battery-powered equipment requiring efficient load management

Current Regulation/Management Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to limited availability status. Confirm RoHS compliance and specific tape-and-reel packaging requirements during ordering. Ensure design compatibility with the 10-UTQFN footprint and verify that the selected current-limiting resistor matches the desired threshold specifications.

Current Regulation/Management Selection Notes

Select this component when a single-channel high-side switch with adjustable current limits is required. Compare against the MAX4995AAVB+ variant if stricter accuracy or different package options are needed. Evaluate thermal performance based on expected load currents and ambient temperatures to ensure operation within the specified junction temperature range.

Current Regulation/Management Part Context

This part belongs to the MAX4995A family of power switches designed for portable applications. It serves as a compact solution for managing power delivery to peripherals. The device integrates protection features typically found in discrete solutions, reducing board space and simplifying circuit design for consumer electronics and industrial control systems.

Current Regulation/Management Replacement Considerations

The MAX4995AAVB+ is a documented substitute within the same product family. Verify pinout compatibility and electrical parameter alignment before substitution. Other variants in the MAX4995 series may offer different packages or accuracy levels but require careful evaluation of functional equivalence.
