MAX6368PKA44+T

Overview

The MAX6368PKA44+T is a low-power voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of up to 5.5 V and features a fixed threshold voltage of 4.38 V for monitoring single input lines. The device provides an active high, open-drain output with a standard reset delay time of 280 ms. It includes battery backup functionality and a chip enable signal for power management control. The component supports manual reset operations and lacks a watchdog timer. It is housed in an SOT-23-8 surface-mount package and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrates battery backup switch capability to maintain system state during power transitions
• Features chip enable gating for precise power consumption control and operational management
• Provides active high open-drain output signaling for flexible logic interface compatibility

Applications

• Microprocessor system voltage supervision
• Battery-powered portable equipment monitoring
• Embedded controller power integrity verification

Procurement Notes

Verify component authenticity through authorized distribution channels due to limited availability status. Confirm package marking and datasheet revision alignment before integration. Check for obsolescence notices or lifecycle restrictions that may impact long-term production support. Ensure storage conditions comply with moisture sensitivity levels specified in the official documentation to prevent package degradation prior to assembly.

Selection Notes

Select this variant when an active high output polarity is required for system logic compatibility. The fixed 4.38 V threshold suits applications monitoring standard 5 V rail voltages. Consider the SOT-23-8 footprint constraints for PCB layout planning. Evaluate the 15 uA operating current against strict power budget requirements for battery longevity optimization in standby modes.
