MAX6365PKA31-T

Overview

The MAX6365PKA31-T is a low-power supervisory circuit in an SOT-23-8 package. It monitors one input voltage with a threshold of 3.094V. The device features a manual reset, active-low open-drain output, and a reset delay time of 280 ms. Operating current is 15 µA. It supports battery backup switching and chip-enable gating. The operating temperature range is -40°C to +85°C.

Feature Summary

• Integrates battery backup control functions for seamless power source transitions
• Provides chip-enable gating to manage system states during power events
• Includes manual reset capability for user-initiated system recovery

Applications

• Microprocessor power-supply monitoring
• Battery-backup control circuits
• Memory write protection systems

Procurement Notes

Verify the exact suffix against official Analog Devices documentation to confirm voltage thresholds and package variants. Confirm availability status as some listings indicate obsolete or limited supply conditions. Ensure compatibility with required operating temperatures and interface specifications before integration.

Selection Notes

Select this component when low quiescent current and integrated battery management are required. The fixed threshold voltage suits specific rail monitoring needs without external resistors. Consider the SOT-23-8 footprint for space-constrained designs requiring manual reset and chip-enable features.

Part Context

This part belongs to the MAX6365P series of supervisory circuits designed for microprocessor applications. It simplifies power management by combining voltage monitoring with battery backup and enable control in a compact surface-mount package.

Replacement Considerations

Check for MAX6365PKA31+T as a potential lead-free variant. Verify functional equivalence with other MAX6365 family members if threshold adjustments are acceptable.
