MAX6365PKA46-T

Overview

The MAX6365PKA46-T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 4.63 V for monitoring a single input. The device provides an active-low, open-drain output with a reset delay time of 280 ms. Key functional attributes include a manual reset capability, battery backup switch, and chip-enable gating. It is housed in an SOT-23-8 package and supports surface-mount installation. The component is designed for operation across a temperature range from -40°C to +85°C, consuming a typical quiescent current of 15 µA.

Feature Summary

• Integrates battery backup switching and chip-enable gating for enhanced system control
• Provides manual reset functionality alongside automatic voltage supervision
• Features low-power architecture suitable for battery-operated applications

Applications

• Portable electronic devices requiring low standby current
• Battery-powered systems needing backup power management
• Microprocessor-based circuits requiring reliable voltage supervision

Procurement Notes

Verify availability status as distribution channels may indicate limited stock or discontinuation. Confirm exact ordering suffixes match the required pinout and electrical specifications. Cross-reference datasheet revisions to ensure compatibility with existing designs. Validate RoHS compliance documentation prior to integration. Check for alternate packages if lead times are extended.

Selection Notes

Select this component when a fixed 4.63 V threshold is required for single-input monitoring. Consider the manual reset feature if user intervention is necessary for system recovery. Ensure the SOT-23-8 package fits the PCB layout constraints. Verify that the open-drain output type aligns with the downstream logic interface requirements.

Part Context

This part belongs to the MAX6365P series of low-power uP supervisors. It shares architectural similarities with other Maxim Integrated supervisory ICs but is distinguished by its specific threshold voltage and manual reset capability. The series is designed for compact, cost-sensitive applications where power efficiency and reliable system resets are critical.

Replacement Considerations

Check for direct substitutes within the MAX6365 family with different threshold voltages. Evaluate MAX6366 variants if watchdog timer functionality is needed instead of manual reset. Verify pin-to-pin compatibility with other SOT-23-8 supervisors before substitution.
