MAX6366LKA31

Overview

The MAX6366LKA31+ is a low-power supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated, housed in an SOT-23-8 surface-mount package. It monitors a single input voltage with a threshold of 3.08 V and features an active high, open-drain output. The device includes a watchdog timer, battery backup switch, and chip enable functionality. Operating from -40°C to +85°C, it draws 15 µA and supports a maximum supply voltage of 5.5 V.

Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Includes battery backup switch capability for power continuity
• Features chip enable gating for power management control

Applications

• Microprocessor reset circuits
• Battery-powered systems requiring supervision
• Portable electronic devices

Procurement Notes

Verify the exact suffix (e.g., +T) for packaging configuration as datasheets may list variants. Confirm availability status directly with authorized distributors, as some listings indicate limited stock or discontinuation. Ensure RoHS compliance documentation matches current manufacturing standards before finalizing procurement orders.

Selection Notes

Select this component when a single-channel supervisor with watchdog and battery backup is required. The 3.08 V threshold suits specific logic families. Verify that the open-drain output aligns with the target microprocessor reset pin requirements. Consider the SOT-23-8 footprint for space-constrained designs.

Part Context

Part of the MAX6366P series, designed for ultra-low-power applications. It complements other Maxim supervisors like the MAX6365 and MAX6367, offering similar features but with distinct threshold voltages and output configurations tailored for different voltage rails and system architectures.

Replacement Considerations

Check MAX6366LKA31+T for tape-and-reel packaging alternatives. Compare with MAX6365LKA31+ if manual reset is not needed. Verify electrical compatibility with MAX6367LKA31+ regarding threshold and output type before substitution.
