MAX6367PKA26+T

Overview

The MAX6367PKA26+T is a low-power supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1.6 V to 5.5 V and features a reset threshold voltage of 2.60 V. The device provides an active-low, push-pull output with a fixed reset delay time of 280 ms. It includes battery backup functionality and chip-enable gating for power management control. The component is housed in an SOT-23-8 package and supports operation across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates battery backup switch capability to maintain system state during power transitions.
• Includes chip-enable gating logic for controlled power sequencing and monitoring.
• Delivers active-low push-pull reset output signals for reliable interface compatibility.

Applications

• Portable electronic devices requiring extended battery life
• Embedded systems needing automated power-on reset sequences
• Battery-powered instrumentation with backup power requirements

Procurement Notes

Verify the specific suffix 'KA26' against official datasheets to confirm the exact threshold voltage and feature set. Confirm RoHS compliance status and AEC-Q100 qualification if automotive use is intended. Check current availability as distribution may be limited or subject to factory special orders. Ensure the SOT-23-8 footprint matches your PCB design constraints before finalizing procurement.

Selection Notes

Select this component when a low quiescent current supervisor with integrated battery backup and chip-enable features is required. Compare the 2.60 V threshold against your system's minimum operating voltage to ensure proper reset timing. Consider the SOT-23-8 package size relative to available board space. Verify that the 280 ms reset delay aligns with your microcontroller's startup requirements.
