MAX6310UK49D3-T

Supervisors Overview

The MAX6310UK49D3-T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It features two monitored inputs with factory-programmed reset thresholds of 3.3 V and 5 V. The device provides an active low, push-pull output and includes a manual reset input. It operates within a supply voltage range up to 5.5 V and consumes 8 µA of operating supply current. The reset delay time is specified at 1.4 ms. The component is housed in a compact SOT-23-5 package suitable for surface mount applications.

Supervisors Feature Summary

• Monitors two independent power supply rails simultaneously
• Provides active low push-pull reset signal output
• Includes manual reset input capability
• Operates with ultra-low supply current consumption

Supervisors Applications

• Monitoring dual voltage rails in portable electronic systems
• Supervising power sequences in embedded microprocessor designs
• Ensuring system stability in battery-operated devices

Supervisors Procurement Notes

Verify the specific suffix D3 against official Analog Devices documentation to confirm the exact threshold configuration and revision level. Confirm availability status as distribution channels may list limited stock or obsolete status. Ensure the SOT-23-5 package compatibility matches your PCB footprint requirements before finalizing procurement orders.

Supervisors Selection Notes

Select this component when simultaneous monitoring of two distinct voltage levels is required without external comparator circuits. The integrated manual reset feature allows for user-initiated system resets. Verify that the 1.4 ms reset delay meets the timing requirements of the target microprocessor or logic family. Ensure the operating temperature range aligns with the intended environmental conditions.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 series of 5-pin, multiple-input programmable reset ICs manufactured by Maxim Integrated, now part of Analog Devices. These devices are engineered to ignore fast transients on monitored supplies while guaranteeing valid reset states down to low supply voltages. The series offers various threshold combinations to suit different power architecture needs.

Supervisors Replacement Considerations

Cross-reference with other MAX6310 variants such as MAX6310EUK33D3-T or MAX6310EUK43D3-T if different threshold configurations are needed. Verify pinout compatibility with existing board layouts. Check for lead-free compliance markings if RoHS standards are mandatory for the assembly process.
