MAX6367HKA31+

Overview

The MAX6367HKA31+ is a low-power supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2.5 V to 5.5 V and features a fixed threshold voltage of 3.08 V for monitoring a single input. The device provides an active-high reset output with an open-drain configuration and includes a battery backup switch. It incorporates a chip-enable gating function and maintains a typical operating current of 15 uA. The component supports a reset delay time of 280 ms and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrates battery backup switching capability to maintain system state during power transitions
• Features chip-enable gating functionality for precise control over supervisory operations
• Provides active-high reset signal with open-drain output structure

Applications

• Microprocessor reset circuits in embedded systems
• Battery-powered portable devices requiring power supervision
• Industrial control systems needing reliable voltage monitoring

Procurement Notes

Verify the exact suffix and package type when sourcing, as variations exist within the MAX6367 family. Confirm RoHS compliance status through official documentation before integration. Check current availability as this specific part number may be subject to limited stock or obsolescence notices. Ensure the supplier provides genuine components with traceable manufacturing data.

Selection Notes

Select this component when a fixed 3.08 V threshold is required for single-input monitoring. Consider the MAX6367 series if chip-enable gating and battery backup are necessary features. Evaluate the SOT-23-8 package constraints against board space requirements. Compare operating current specifications against other supervisors if ultra-low power consumption is critical for the application design.

Part Context

This component belongs to the MAX6367H series of low-power supervisory circuits designed for portable and battery-operated applications. It shares functional similarities with the MAX6366 and MAX6368 families but differs in specific feature sets such as watchdog timers or adjustable thresholds. The H-series designation typically indicates specific performance characteristics within the broader Maxim Integrated supervisor portfolio.
