MAX6365LKA29+T

Overview

The MAX6365LKA29+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of up to 5.5 V and features a fixed threshold voltage of 2.93 V with an overvoltage threshold of 3 V. The device provides an active-low, push-pull output and includes manual reset functionality. It incorporates battery backup switching and chip-enable gating capabilities. The reset delay time is specified at 280 ms, and the quiescent current is 15 uA. It functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrates battery backup switching for seamless power transition management
• Includes chip-enable gating to control system activity during low-power states
• Provides manual reset input for user-initiated system recovery

Applications

• Microprocessor power supply monitoring in embedded systems
• Battery-powered devices requiring backup power management
• Industrial control circuits needing reliable voltage supervision

Procurement Notes

Verify the complete part number including suffixes against official Analog Devices documentation to ensure correct threshold voltage and package configuration. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as availability may vary by region and production cycle.

Selection Notes

Select this component when a single-channel supervisor with battery backup and chip-enable features is required. Ensure the 2.93 V threshold matches the monitored rail voltage. Consider the SOT-23-8 package constraints and the 15 uA quiescent current suitability for low-power designs compared to higher-current alternatives.

Part Context

This part belongs to the MAX6365L series of low-power microprocessor supervisors. It is designed for applications requiring precise voltage monitoring with additional control features like chip-enable gating. The series is characterized by low standby current and robust performance in industrial environments.

Replacement Considerations

Check for direct pin-compatible substitutes within the MAX6365 family with different threshold voltages if voltage levels differ. Verify functional equivalence for battery backup and chip-enable features before substituting.
