MAX6361PUT26+T

Overview

The MAX6361PUT26+T is a low-power microprocessor 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 2.63 V. The device provides an active-low, open-drain output with a reset timeout period of 150 ms. It consumes only 15 uA of operating supply current and includes manual reset functionality. The component is housed in a SOT-23-6 package and supports battery backup switching. It functions as a single-input voltage supervisor without watchdog timer capabilities.

Feature Summary

• Provides reliable power system monitoring for microprocessors through a dedicated supervisory circuit.
• Includes manual reset input capability allowing for user-initiated system resets.
• Supports battery backup switching to maintain system integrity during power transitions.

Applications

• Microprocessor power supply supervision
• Battery backup system monitoring
• Low-power embedded controller reset management

Procurement Notes

Verify the specific suffix codes against official datasheets to ensure correct threshold voltage and output polarity configurations. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as availability may vary by region. Ensure the selected package matches the intended PCB footprint requirements.

Selection Notes

Select this component when a fixed 2.63 V threshold is required for single-rail monitoring. Consider the 150 ms reset delay and active-low output characteristics for compatibility with target logic levels. Evaluate the 15 uA quiescent current against strict power budget constraints. Verify that the absence of a watchdog timer meets the application's safety requirements.

Part Context

This part belongs to the MAX6361 series of low-power MPU supervisors. It shares the SOT-23-6 form factor with other variants in the family but differs in threshold voltage settings and output active states. The series is designed for applications requiring minimal standby current and compact packaging for portable electronics.

Replacement Considerations

Check for MAX6361PUTxx+T variants with different threshold voltages if the 2.63 V setting is unsuitable. Verify pinout compatibility with alternative supervisory ICs from the same manufacturer before substitution.
