MAX6363PUT46+T

Overview

The MAX6363PUT46+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 a fixed reset threshold voltage of 4.6V. The device provides an active-low, open-drain output with a typical reset delay time of 280ms. It is housed in a compact SOT-23-6 surface-mount package and supports manual reset functionality. The circuit draws a maximum quiescent current of 15µA and is rated for operation across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrates a precision voltage monitor with a fixed 4.6V threshold for reliable system supervision
• Supports manual reset input to allow external control over the reset state
• Delivers an active-low, open-drain output signal compatible with standard logic interfaces
• Optimized for ultra-low power consumption with a quiescent current of 15µA

Applications

• Microprocessor (MPU) power supply monitoring
• Battery-powered embedded systems requiring low standby current
• Portable electronic devices needing voltage supervision
• Industrial control units operating in harsh environments

Procurement Notes

Verify the exact suffix '46' corresponds to the 4.6V threshold variant during sourcing. Confirm RoHS compliance status as indicated in official documentation. Check for obsolescence notices or lifecycle changes directly from Analog Devices. Ensure the SOT-23-6 footprint matches your PCB design constraints before finalizing procurement.

Selection Notes

Select this component when a fixed 4.6V threshold is required for system supervision. Consider the open-drain output configuration for level shifting compatibility. Evaluate the 15µA quiescent current against battery life requirements. Verify that the SOT-23-6 package size fits within the available board space constraints.

Part Context

This part belongs to the MAX6363 family of low-power microprocessor supervisors. The series offers various threshold voltages and output configurations to suit different system requirements. Analog Devices acquired Maxim Integrated, consolidating these product lines under one manufacturer portfolio for unified support and datasheet management.

Replacement Considerations

Check for direct pin-to-pin replacements within the MAX6363 family with different threshold suffixes. Verify functional equivalence if substituting with other MPU supervisor ICs from Analog Devices or third-party manufacturers.
