MAX4995BAVB+T

Current Regulation/Management Overview

The MAX4995BAVB+T is a single-channel power distribution switch IC from the MAX4995A-C series, 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 between 50 mA and 600 mA. The device exhibits a maximum on-resistance of 350 mΩ, with typical values as low as 130 mΩ. It supports fast switching times, with both turn-on and turn-off delays capped at 120 µs. Packaged in a compact 10-UTQFN (1.4x1.8 mm) footprint, it is designed for surface-mount installation and functions reliably across an extended temperature range of -40°C to +125°C.

Current Regulation/Management Feature Summary

• Features a programmable current-limit function allowing adjustment from 50 mA to 600 mA via external components.
• Provides low on-resistance characteristics to minimize power loss during conduction.
• Supports rapid switching transitions with defined turn-on and turn-off delay times.

Current Regulation/Management Applications

• USB power distribution networks requiring overcurrent protection
• Portable electronic devices needing efficient power management
• Industrial control systems utilizing power switches

Current Regulation/Management Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and specific lot traceability upon receipt. Ensure storage conditions adhere to moisture sensitivity level requirements to maintain package integrity before soldering.

Current Regulation/Management Selection Notes

Select this part when a single-channel switch with high-side configuration and adjustable current limiting is required. Consider the 10-UTQFN package constraints for PCB layout. Evaluate thermal performance based on load current and ambient temperature to ensure operation within the specified junction temperature limits.
