MAX6366LKA31+T

Overview

The MAX6366LKA31+T is a low-power microprocessor supervisory circuit in an SOT-23-8 package. It monitors a single voltage input with a fixed threshold of 3.08 V and operates within a supply range of 0 to 5.5 V. The device features an active-low, push-pull output and provides a reset timeout delay of 150 ms. It includes battery backup switching functionality and chip-enable gating for power management control. The component supports manual reset inputs and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrates battery backup switching for seamless power source transitions
• Provides chip-enable gating to manage system power states efficiently
• Delivers active-low push-pull output for direct logic interface compatibility

Applications

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

Procurement Notes

Verify the specific suffix 'K' indicates the SOT-23-8 package configuration and '+T' denotes tape-and-reel packaging. Confirm the 'A31' code corresponds to the 3.08 V threshold voltage before procurement. Ensure the component meets RoHS compliance requirements for your assembly process. Check current availability status as distribution may vary by region.

Selection Notes

Select this part when a fixed 3.08 V threshold is required for voltage supervision. Choose the SOT-23-8 package for compact surface-mount designs. Consider the 150 ms reset delay for timing-sensitive applications. Verify that the active-low output polarity matches the target controller's input requirements.

Part Context

This component belongs to the MAX6366 series of low-power supervisory circuits designed for microprocessor systems. It simplifies power-supply monitoring and battery-backup control functions. The series offers various threshold options and package configurations to suit different design constraints while maintaining low quiescent current consumption.

Replacement Considerations

Check for MAX6366 variants with different threshold codes if the 3.08 V level is unsuitable. Verify pinout compatibility with alternative SOT-23-8 supervisors. Ensure replacement parts support the same battery backup and chip-enable features.
