MAX6361HUT23+

Overview

The MAX6361HUT23+ is a low-power microprocessor supervisory circuit manufactured by Analog Devices / Maxim Integrated. It operates within a supply voltage range of 1.2 V to 5.5 V and features a fixed reset threshold voltage of 2.3 V. The device provides an active high, open-drain output with a standard reset delay time of 280 ms. It includes a manual reset input and a battery backup switch function while lacking a watchdog timer. The component is housed in a compact SOT-23-6 package and supports surface mount installation. It functions reliably across an industrial temperature range from -40°C to +85°C with a quiescent current of 15 µA.

Feature Summary

• Integrates a manual reset input for user-initiated system control alongside automatic voltage monitoring capabilities.
• Features a dedicated battery backup switch pin to manage power source transitions between main and backup supplies.
• Delivers an active high, open-drain reset signal to ensure compatibility with various logic families.

Applications

• Low-power microprocessor systems requiring reliable power-on reset sequencing
• Battery-operated devices utilizing the integrated battery backup switch functionality
• Embedded controllers needing manual reset inputs for service or debugging

Procurement Notes

Verify the specific suffix UT23 confirms the 2.3 V threshold and SOT-23-6 package configuration. Confirm RoHS compliance status through official manufacturer documentation. Check current availability as distribution channels may list limited stock or end-of-life statuses. Ensure the active high open-drain output aligns with your target logic interface requirements before finalizing procurement.

Selection Notes

Select this component when a fixed 2.3 V threshold is required for precise voltage monitoring. The inclusion of a manual reset input distinguishes it from variants lacking this feature. Verify that the open-drain output structure suits your pull-up resistor design. Consider the 15 µA quiescent current for strict power budget constraints in portable applications.

Part Context

This part belongs to the MAX6361 series of low-power MPU supervisors. It shares the family's core architecture but differs in threshold voltage and package type from other suffixes like H or P. The MAX6361 series is designed for general-purpose voltage supervision in consumer and industrial electronics where size and power consumption are critical factors.

Replacement Considerations

Cross-reference with MAX6361HUT23+T for tape-and-reel packaging options. Verify functional equivalence with MAX6361LUT23+ if active low outputs are acceptable instead of active high.
