MAX4995AAVB+T

Current Regulation/Management Overview

The MAX4995AAVB+T is a single-channel high-side power distribution switch IC designed for USB applications. 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 via an external resistor. The device incorporates a maximum on-resistance of 350 mOhms and supports fast switching with typical rise and fall times of 120 µs. Packaged in a compact 10-UTQFN (1.4x1.8 mm) surface-mount format, it functions reliably across an extended industrial temperature range of -40°C to +125°C.

Current Regulation/Management Feature Summary

• Programmable current limiting capability allows precise load protection adjustment through a single external resistor.

Current Regulation/Management Applications

• USB port power distribution
• Peripheral device overcurrent protection

Current Regulation/Management Procurement Notes

Verify component authenticity by checking the manufacturer's marking code against official documentation. Confirm the specific suffix matches the required package variant. Ensure compliance with RoHS directives if applicable to your region. Validate that the received lot corresponds to the ordered revision level. Cross-reference the part number with authorized distributor catalogs to confirm availability status.

Current Regulation/Management Selection Notes

Select this component when a single-channel high-side switch with adjustable current limits is required. It is suitable for designs needing protection between 50 mA and 600 mA. Consider the UTQFN-10 package for space-constrained PCB layouts. Verify that the input voltage range of 1.7 V to 5.5 V aligns with the system power rails. Ensure thermal management meets the requirements for the expected load conditions.

Current Regulation/Management Part Context

This part belongs to the MAX4995A series of USB power switches. It serves as a high-side switch solution for distributing power to downstream peripherals. The series offers various package options including SOT-23-6 and UTQFN variants. These devices are engineered to provide robust overcurrent protection for USB-based systems.

Current Regulation/Management Replacement Considerations

The MAX4995CAVB+T is a verified alternative within the same family. Both parts share identical electrical characteristics and pin configurations. They utilize the same 10-UTQFN package. Designers may substitute one for the other without schematic modifications.
