MAX6365HKA29+T

Overview

The MAX6365HKA29+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It provides reset and watchdog timer functions for digital systems. The device features a fixed output threshold voltage of 2.93V, ensuring reliable monitoring of supply rails within the specified operating range. It operates with supply voltages from 1.6V to 5.5V. Key electrical characteristics include a low quiescent current consumption and a precise reset delay time. The component is housed in an 8-pin SOIC package, suitable for space-constrained applications requiring robust system supervision.

Feature Summary

• Provides active-low reset signal generation based on monitored supply voltage levels
• Integrates a manual reset input for user-initiated system restarts
• Includes a watchdog timer function to detect software malfunctions
• Ensures stable operation during power-up and power-down transitions

Applications

• Portable electronic devices requiring low-power supervision
• Embedded systems needing reliable reset management
• Industrial control units with strict voltage monitoring requirements

Procurement Notes

Verify the exact part number suffix against official manufacturer documentation to confirm pinout and electrical specifications. Ensure the component source is authorized to guarantee authenticity and traceability. Check for RoHS compliance markings if environmental regulations apply to your deployment. Confirm package type matches your PCB footprint design requirements before ordering.

Selection Notes

Select this component when a fixed 2.93V threshold is appropriate for the target supply rail. Consider the quiescent current requirements relative to the system's power budget. Evaluate the need for a watchdog timer versus simple reset functionality. Ensure the operating temperature range meets the environmental conditions of the intended application site.

Part Context

This part belongs to the MAX6365 family of supervisory circuits designed for general-purpose voltage monitoring. These devices are engineered to provide essential protection for microprocessors and memory systems. The family offers various threshold voltages and package options to suit different design constraints. This specific variant focuses on cost-effective supervision for standard logic families.

Replacement Considerations

Direct replacements must match the 2.93V threshold and SOIC-8 package. Verify compatibility of reset delay times and watchdog intervals with existing firmware timing constraints. Ensure equivalent supply voltage ranges and operating temperature specifications are maintained for seamless integration.
