MAX6367PKA26+

Overview

The MAX6367PKA26+ is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.5 V to 5.5 V and features a fixed reset threshold voltage of 2.63 V. The device provides an active-low, push-pull reset output with a typical reset delay time of 150 ms. It incorporates a battery backup switch for seamless power transition and includes a chip-enable gating function for power management. Packaged in an SOT-23-8 surface-mount case, it supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Integrates a battery backup switch to maintain system integrity during power transitions
• Includes chip-enable gating functionality for enhanced power control
• Delivers an active-low push-pull reset signal with defined timing characteristics

Applications

• Microprocessor system supervision
• Battery-powered electronic devices
• Portable instrumentation monitoring

Procurement Notes

Verify component authenticity through authorized channels due to potential limited availability. Confirm package marking and datasheet alignment against the official Analog Devices specification sheet. Ensure environmental compliance documentation matches project requirements before finalizing procurement orders.

Selection Notes

Select this part when a fixed 2.63 V threshold is required for system monitoring. The integrated battery backup switch simplifies design compared to discrete solutions. Verify that the SOT-23-8 footprint aligns with existing PCB layout constraints and thermal requirements.

Part Context

This component belongs to the MAX6367P series of low-power supervisors. It shares functional similarities with other Maxim Integrated supervisory circuits but is distinguished by its specific 2.63 V threshold and inclusion of both battery backup switching and chip-enable gating capabilities within a compact eight-pin package.
