MAX6362PUT31

Overview

The MAX6362PUT31 is a microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within an input voltage range of 2.5V to 5.5V and features a fixed reset threshold of 3.08V. The device provides an active-low, open-drain reset output with a programmable reset delay time selectable between 50ms and 1.4s. It includes a manual reset input and supports battery backup switching. The component functions in the -40°C to +85°C temperature range and is housed in an 8-pin TSSOP package.

Feature Summary

• Monitors power supply voltage levels to assert system reset when thresholds are breached
• Includes manual reset input for external control of the reset state
• Supports battery backup switching to maintain supervision during power transitions
• Features programmable reset delay times to accommodate specific startup requirements

Applications

• Portable electronic devices requiring low-power supervision
• Battery-operated instrumentation systems
• Embedded controllers needing reliable power-on reset sequences
• Industrial control units operating in extended temperature environments

Procurement Notes

Verify the exact suffix 'PUT31' against official Analog Devices documentation to confirm the specific reset delay configuration and package variant. Ensure compatibility with your board's voltage domain and thermal constraints. Cross-reference the manufacturer part number directly with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status if required for your manufacturing standards.

Selection Notes

Select this component when a fixed 3.08V threshold is appropriate for the monitored rail. Consider the programmable delay feature if the system requires specific timing margins during power-up. Evaluate the low quiescent current consumption if battery life is a critical design constraint. Verify that the TSSOP-8 package fits within the available PCB footprint and assembly capabilities.

Part Context

This part belongs to the MAX636x series of microprocessor supervisory circuits from Maxim Integrated. These devices are designed to provide robust power management monitoring for complex digital systems. The series offers various threshold voltages and package options to suit different application needs while maintaining low power consumption and high accuracy.

Replacement Considerations

Consult the official datasheet for direct pin-compatible alternatives within the MAX636x family. Verify that any substitute maintains the same 3.08V threshold and reset delay characteristics. Ensure the replacement package matches the existing board layout constraints.
