MAX6361PUT46+

Overview

The MAX6361PUT46+ is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. 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 signal with a typical reset delay time of 280ms. It supports manual reset functionality via an external push-button switch and includes a battery backup pin for maintaining state during power transitions. The component is available in a compact SOT-23-6 surface-mount package and is rated for operation across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Provides reliable system reset monitoring with a fixed 4.6V threshold voltage
• Includes manual reset input capability for user-initiated system restarts
• Features a dedicated battery backup pin to preserve data during power loss events

Applications

• Microprocessor and microcontroller power supply supervision
• Portable electronic devices requiring low quiescent current
• Battery-operated systems needing backup power management

Procurement Notes

Verify the specific suffix 'PUT46' against official Analog Devices documentation to confirm the exact threshold voltage and package configuration. Ensure compatibility with your board's thermal requirements and operating temperature range. Confirm availability status as distribution channels may vary. Always reference the latest datasheet for pinout and electrical characteristics before finalizing procurement.

Selection Notes

Select this component when a fixed 4.6V reset threshold is required for systems powered between 1.2V and 5.5V. Consider its low power consumption and manual reset feature if user intervention is needed. Verify that the SOT-23-6 package fits your PCB layout constraints. Compare against other MAX6361 variants if different threshold voltages or output types are necessary for your specific application design.

Part Context

This part belongs to the MAX6361 series of low-power microprocessor supervisors. The series is designed to monitor voltage levels in digital systems. Variants within the family differ primarily in reset threshold voltages and output configurations. The MAX6361PUT46+ specifically targets applications requiring precise supervision at higher voltage levels within the standard single-supply range.

Replacement Considerations

Check for direct cross-references in Analog Devices' product change notices. Other MAX6361 variants with different threshold suffixes may serve as functional substitutes if the voltage level matches. Verify pin-to-pin compatibility with alternative supervisory ICs from other manufacturers before substitution.
