MAX6366LKA46+T

Overview

The MAX6366LKA46+T is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 4.63 V. The device provides an active low, push-pull output with a minimum reset timeout of 150 ms. It includes battery backup switching functionality and supports manual reset operations. The component is designed for surface mount installation in SOT-23-8 packages and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides precise voltage supervision with a fixed 4.63 V threshold
• Includes battery backup switching to maintain system integrity during power transitions
• Supports manual reset input for controlled system recovery

Applications

• Portable electronic devices requiring low-power monitoring
• Battery-operated systems needing backup switching capabilities
• Embedded controllers requiring reliable voltage supervision

Procurement Notes

Verify current availability status as the component may be discontinued or subject to limited distribution channels. Confirm package type and RoHS compliance details before procurement. Ensure compatibility with existing board designs regarding SOT-23-8 footprint and electrical specifications. Check for authorized distributor listings to avoid counterfeit sources.

Selection Notes

Select this component when a fixed 4.63 V threshold is required for voltage monitoring applications. Consider its low quiescent current and battery backup feature for power-sensitive designs. Verify that the SOT-23-8 package fits the available PCB space. Ensure the operating temperature range meets the environmental requirements of the target application.

Part Context

This part belongs to the MAX6366 series of uPower Supervisors from Maxim Integrated, now part of Analog Devices. These circuits are designed for low-power applications where precise voltage monitoring is critical. The series offers various threshold voltages and package options to suit different design constraints while maintaining high accuracy and reliability.

Replacement Considerations

Check for direct pin-compatible substitutes within the MAX6366 family with adjusted thresholds. Verify if newer generations from Analog Devices offer improved performance or availability. Ensure any replacement maintains the same output type and reset delay characteristics.
