MAX6467XS26D7

Overview

The MAX6467XS26D7+T is a voltage supervisory reset circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1.8 V to 5 V and features an overvoltage threshold of 2.603 V. The device provides an active low, open-drain output with a manual reset capability and a fixed reset delay time of 1.8 s. It consumes 7 uA of operating current and dissipates up to 245 mW of power. Designed for surface mount installation in an SC-70-4 package, it supports a wide operating temperature range from -40 C to +125 C.

Feature Summary

• Provides precise voltage supervision with a dedicated overvoltage detection threshold
• Features manual reset functionality for controlled system initialization
• Delivers active low open-drain output signal for microprocessor interfacing
• Operates efficiently with ultra-low quiescent current consumption

Applications

• Microprocessor (MPU) supervisory reset circuits
• Voltage monitoring in portable electronic devices
• System protection against overvoltage conditions
• Power management in battery-operated equipment

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and specific suffix designations match project requirements. Check for obsolescence notices or lifecycle changes before finalizing procurement plans. Ensure packaging format aligns with automated assembly capabilities.

Selection Notes

Select this component when a single-channel voltage supervisor with overvoltage protection is required. The SC-70-4 package suits space-constrained designs. Verify that the 2.603 V overvoltage threshold meets system safety margins. Consider the 1.8 s reset delay duration relative to processor startup times. Evaluate the 7 uA current draw against total system power budgets.
