MAX14728EWV+T

Overview

The MAX14728EWV+T is a dual-input, bidirectional overvoltage protector manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors two independent input channels with a threshold voltage of 10 V and an overvoltage threshold of 10.15 V. The device features open-drain outputs and operates within a supply voltage range up to 28 V. It consumes 230 uA of working current and maintains an accuracy of 2%. The component supports surface mount installation in a WLP-30 package and functions reliably across a temperature range of -40 C to +85 C.

Feature Summary

• Provides bidirectional protection for dual independent input channels against overvoltage conditions
• Generates open-drain output signals when monitored voltages exceed specified thresholds
• Operates without manual reset or watchdog timer functionality

Applications

• Monitoring critical power rails in industrial control systems
• Protecting sensitive electronics in automotive applications
• Overvoltage detection in consumer electronic devices

Procurement Notes

Verify that the specific suffix T indicates reel packaging rather than cut tape when sourcing. Confirm RoHS compliance status through official documentation as required for your assembly process. Ensure the supplier provides valid traceability for the Analog Devices / Maxim Integrated origin. Check for any regional distribution restrictions that may apply to this supervisory circuit part number.

Selection Notes

Select this component when dual-channel voltage supervision is required with high accuracy. The 2% accuracy ensures precise threshold detection for sensitive loads. Consider the WLP-30 package size for space-constrained designs. Verify that the 28 V maximum supply rating aligns with your system's peak voltage requirements.

Part Context
