MAX6366PKA31+T

Overview

The MAX6366PKA31+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors a single voltage input with a threshold of 3.08 V and features an active-low, open-drain output. The device includes a watchdog timer, battery backup switch, and chip-enable gating. It operates within a supply voltage range up to 5.5 V and consumes only 15 uA of quiescent current. The reset delay time is specified at 280 ms, and the overvoltage threshold is 4.75 V. It is housed in an SOT-23-8 package and functions between -40°C and +85°C.

Feature Summary

• Integrates a watchdog timer for system fault detection
• Includes battery backup functionality for seamless power transitions
• Supports chip-enable gating for power management control

Applications

• Microprocessor system monitoring
• Battery-powered portable devices
• Industrial control systems requiring voltage supervision

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Check for obsolescence notices or lifecycle changes as availability may be restricted. Ensure packaging specifications match design needs, noting that tape-and-reel options are available for automated assembly processes.

Selection Notes

Select this part when a single-channel supervisor with integrated watchdog and battery backup is required. The 3.08 V threshold suits applications monitoring standard logic supplies. Consider the SOT-23-8 package for space-constrained designs. Verify that the active-low open-drain output aligns with the target microprocessor reset input requirements.

Part Context

This component belongs to the MAX6366P series of low-power supervisors from Maxim Integrated. The series offers various threshold voltages and package options to accommodate different system voltage levels. The 'T' suffix indicates tape-and-reel packaging, suitable for high-volume surface-mount production lines.

Replacement Considerations

Check for MAX6366PKA31+ (cut tape) if reel quantity is not needed. Other MAX6366 variants with different thresholds may serve as functional substitutes if voltage levels differ.
