MAX6361PUT29+T

Overview

The MAX6361PUT29+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of up to 5.5 V and features a fixed threshold voltage of 2.93 V for monitoring power rails. The device provides an active-low, open-drain reset output with a typical reset delay time of 280 ms. It includes a manual reset input and battery backup functionality but lacks a watchdog timer or chip enable signal. Designed for surface-mount installation in SOT-23-6 packages, it supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Provides reliable system reset generation through a dedicated manual reset input pin.
• Integrates battery backup switching to maintain supervision during primary power loss.
• Delivers an active-low open-drain reset signal compatible with standard logic interfaces.

Applications

• Microprocessor power supply monitoring
• Battery-operated electronic systems
• Industrial control board supervision

Procurement Notes

Verify the exact suffix configuration against official datasheets to ensure correct threshold voltage and package type. Confirm availability status as distribution channels may list limited stock or end-of-life statuses. Cross-reference manufacturer part numbers directly to avoid substitution errors with similar series components.

Selection Notes

Select this component when a fixed 2.93 V threshold is required for single-input voltage monitoring. Consider the SOT-23-6 footprint constraints and the necessity for manual reset capability. Evaluate the absence of a watchdog timer if software fault detection is needed elsewhere in the design.

Part Context

This part belongs to the MAX6361H series of low-power MPU supervisors. It shares architectural similarities with other Maxim Integrated supervisory circuits but is distinguished by its specific threshold voltage and lack of integrated watchdog features compared to higher-function variants in the broader portfolio.

Replacement Considerations

MAX6361PUT29+T is functionally equivalent to MAX6361PUT29+ without the tape-and-reel suffix. Verify compatibility with MAX6363PUT29+T if manual reset inputs are not utilized, noting differences in output drive types.
