MAX6363PUT26

Overview

The MAX6363PUT26 is a low-power microprocessor supervisory circuit manufactured by Analog Devices / Maxim Integrated. It monitors a single voltage input and provides an active-low, open-drain reset output with a fixed threshold of 2.63V. The device operates within a supply voltage range up to 5.5V and features a typical reset delay time of 280ms. It includes battery backup functionality and consumes only 15µA of operating current. The component is housed in a compact SOT-23-6 surface-mount package and supports operation across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Provides reliable system reset for microprocessors when monitored voltage drops below the specified threshold
• Integrates battery backup switch capability to maintain system integrity during power transitions
• Designed for ultra-low power consumption suitable for portable and battery-operated applications

Applications

• Microprocessor (MPU) supervision in embedded systems
• Portable electronic devices requiring low standby current
• Industrial control systems needing robust voltage monitoring

Procurement Notes

Verify the specific suffix 'PUT26' against official Analog Devices documentation to confirm the exact threshold voltage and package variant. Confirm RoHS compliance status and lead-free specifications directly from the manufacturer datasheet before integration. Ensure compatibility with existing board layouts regarding the SOT-23-6 footprint and pin configuration.

Selection Notes

Select this component when a fixed 2.63V threshold is required for MPU supervision without manual reset inputs. Consider the open-drain output type for compatibility with various logic levels. Evaluate the 15µA quiescent current against system power budgets. Verify that the 280ms timeout meets the startup requirements of the target processor.

Part Context

This part belongs to the MAX6363P series of low-power microprocessor supervisors. It is designed to replace older supervisor ICs in space-constrained designs. The series offers various threshold options and package types to suit different application needs while maintaining consistent low-power performance characteristics.

Replacement Considerations

Consult official cross-reference lists for direct replacements. Verify that any substitute maintains the same SOT-23-6 package, 2.63V threshold, and open-drain output polarity to ensure pin-to-pin compatibility.
