MAX6368PKA26-T

Overview

The MAX6368PKA26-T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.2V to 5.5V and features an adjustable reset threshold voltage of 2.6V. The device provides a manual reset input, a watchdog timer with a timeout period of 1.4 seconds, and a battery backup switch. It utilizes a Chip Enable gating function and offers an active high/open drain output type. The component is housed in an SOT-23-8 package and supports operation temperatures from -40°C to +85°C.

Feature Summary

• Integrates a watchdog timer with a fixed 1.4-second timeout period for system reliability.
• Includes a battery backup switch to manage power transitions between main and backup supplies.
• Features Chip Enable gating to control the supervisory circuit's active state.

Applications

• Embedded systems requiring reliable power supervision
• Microprocessor-based designs needing watchdog functionality
• Battery-powered devices utilizing backup power switching

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when sourcing. Confirm the exact threshold voltage variant matches the design requirement, as the MAX6368 series includes multiple voltage options. Check current availability status as distribution may vary by region.

Selection Notes

Select this component for applications requiring integrated watchdog and battery backup functions in a compact SOT-23-8 package. Ensure the 2.6V threshold aligns with the monitored rail voltage. Consider the active high output polarity and open-drain configuration for interface compatibility with the target logic levels.

Part Context

This part belongs to the MAX6368P family of low-power uP supervisors. These circuits are designed to monitor single-supply voltages and provide robust protection through reset generation, watchdog timing, and battery management capabilities within a small footprint suitable for portable electronics.

Replacement Considerations

Cross-reference with other MAX6368 variants sharing the same package and functional block diagram but differing in threshold voltage or output polarity. Verify pinout compatibility before substitution.
