MAX6361PUT23+

Overview

The MAX6361PUT23+ 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 2.5 V to 5.5 V and features a fixed threshold voltage of 2.5 V. The device provides an active high, open-drain output with a reset delay time of 280 ms. It includes a battery backup switch for seamless power transition monitoring. The component draws a typical operating supply current of 15 uA and functions reliably across an industrial temperature range from -40°C to +85°C. Packaged in a compact SOT-23-6 surface-mount format, it lacks manual reset or watchdog timer capabilities.

Feature Summary

• Provides reliable voltage supervision with an active high open-drain output for clear status indication
• Integrates a battery backup switch to monitor power source transitions without external components
• Designed for ultra-low power consumption suitable for battery-operated embedded systems

Applications

• Microprocessor system power monitoring
• Battery backup power switching circuits
• Portable electronic device power management

Procurement Notes

Verify the exact suffix and manufacturer documentation when sourcing this component. Confirm that the specific part number matches the required 2.5 V threshold and active high output configuration. Check for RoHS compliance details as indicated in official datasheets. Ensure compatibility with the target PCB footprint and thermal requirements before integration into the design.

Selection Notes

Select this component when an active high output signal is required for system supervision. It is appropriate for designs needing a dedicated battery backup monitoring function integrated into the supervisor. Consider the 280 ms reset delay and 15 uA quiescent current against system power budgets. Verify that the 2.5 V threshold aligns with the monitored rail voltage levels.

Part Context

This device belongs to the MAX6361P series of low-power MPU supervisors. It shares the SOT-23-6 package form factor with other variants in the family but differs in output polarity and threshold settings. The series is designed for general-purpose voltage monitoring in portable and industrial applications requiring minimal board space and low standby current.

Replacement Considerations

Cross-reference with other MAX6361 variants for different thresholds or output polarities. Verify pinout compatibility if substituting with similar supervisory ICs from other manufacturers. Ensure the replacement supports the same battery backup functionality and operating temperature range.
