MAX4995AAVB+

Current Regulation/Management Overview

The MAX4995AAVB+ is a high-side power distribution switch IC from the MAX4995A series, manufactured by Analog Devices Inc./Maxim Integrated. It features a single output with a programmable current limit adjustable between 50 mA and 600 mA. The device operates within a supply voltage range of 1.7 V to 5.5 V and supports surface-mount installation in a 10-UTQFN package (1.4x1.8 mm). Key electrical parameters include a maximum on-resistance of 350 mOhms, a maximum run time of 120 us, and a maximum off time of 120 us. It functions reliably across an extended temperature range from -40°C to +125°C.

Current Regulation/Management Feature Summary

• Programmable current limiting capability allows precise control over load protection thresholds.
• High-side switching architecture enables direct connection to positive power rails for efficient power distribution.
• Integrated thermal and electrical protection mechanisms ensure safe operation under fault conditions.

Current Regulation/Management Applications

Current Regulation/Management Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for restricted substance declarations prior to integration. Ensure storage conditions adhere to moisture sensitivity level requirements to maintain package integrity during assembly processes.

Current Regulation/Management Selection Notes

Select this component when designing circuits requiring adjustable current limits for single-channel high-side applications. Consider the 10-UTQFN footprint for space-constrained layouts. Evaluate the 350 mOhm on-resistance against system efficiency targets and verify that the 1.7 V to 5.5 V input range aligns with the available power supply infrastructure.
