MAX6367PKA44+

Overview

The MAX6367PKA44+ is a low-power supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1.2V to 5.5V and features a fixed reset threshold voltage of 4.40V. The device provides an active-low, push-pull output with a typical reset delay time of 280ms. It incorporates a battery backup switch for seamless power transition and includes a chip-enable gating function. 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 a battery backup switch to maintain system integrity during power transitions
• Features chip-enable gating functionality for precise control over supervisor operation
• Delivers an active-low push-pull reset signal with defined delay characteristics

Applications

• Portable electronic devices requiring low-power monitoring
• Battery-operated systems needing backup switching capabilities
• Embedded controllers requiring supervised power-up sequences

Procurement Notes

Verify the specific suffix 'KA44' against official datasheets to confirm the exact threshold voltage and package configuration. Confirm availability status as distribution channels may list limited stock or obsolete status. Ensure compatibility with existing PCB footprints for the SOT-23-8 package before procurement.

Selection Notes

Select this component when a fixed 4.40V threshold is required for system supervision. Consider the integrated battery backup feature if uninterrupted operation during power switchover is critical. Evaluate the low quiescent current requirements against the application's power budget constraints.

Part Context

This part belongs to the MAX6367P series of uPower Supervisors. These circuits are designed for applications demanding minimal power consumption while providing reliable voltage monitoring. The series typically offers various threshold options and packaging styles to suit diverse embedded design needs.

Replacement Considerations

Consult official cross-reference lists for direct replacements. Verify that any substitute maintains the same SOT-23-8 footprint, 4.40V threshold, and battery backup functionality.
